7th Class Social 7th Lesson Mughal Empire InText Questions and Answers

7th Class Social Textbook Page No. 5

Question 1.
Collect some tales about Akbar – Birbal.
Answer:
1. The Crows in The Kingdom :
On one fine sunny day, Akbar and Birbal were taking a leisurely walk in the palace gardens. Suddenly, Akbar thought of testing Birbal’s wits by asking him a tricky question. Emperor asked Birbal, “How many crows are there in our kingdom?” Birbal could sense the amusement in the king’s voice, and within a few minutes Birbal replied, “My king, there are eighty thousand nine hundred and seventy-one crows in our kingdom”. Surprised and amazed, Akbar further tested Birbal, “What if we have more crows?” Birbal replied, “Oh, then the crows from the other kingdoms must be visiting us”.” What if there are lesser crows?” asked Akbar. “Well, then some of our crows must be visiting other kingdoms”, replied Birbal with a grin on his face. Akbar smiled at Birbal’s great sense of humour and wit.

Moral :There is always a solution if one thinks with ease.

2. Birbal’s Khichadi :
Once on a cold winter day, Akbar and Birbal were walking by a lake. Akbar stopped and put his finger into the freezing water and immediately took it out . saying, “I don’t think anyone can sustain a night in this cold water”. Birbal took that as a challenge and said that he would find someone who can do it. Akbar promised a sum of 1000 gold coins to whoever could spend a night standing in the cold water of the lake. Soon, Birbal found a poor man who agreed to undertake the challenge for the 1000 gold coins. Guarded by two royal guards, the poor man spent the entire night standing in the freezing water.

In the morning, the paor man was taken to court for the reward. On being asked by the king how he could stand in freezing water/the man replied, “My lord, I kept looking at a lamp that was burning at a distance, and spent my entire night looking at it”. On learning this, the emperor said, “This man is not worthy of the reward as he could manage to stand in the lake because he was getting warmth from the lamp”. The poor man felt doomed and heart-broken. He reached out to Birbal for help.

Birbal didn’t go to the court the next day. Akbar visited Birbal to find the reason. To his amusement, the King found Birbal sitting beside the fire with a pot hanging almost 6 feet above it. On being enquired, Birbal said, “I am cooking khichadi, my lord”. Akbar started laughing and said that was impossible. Birbal said, “It is possible my King. If a poor man can stay warm by simply looking at the lamp burning at a distance, I can cook this khichadi the same way.” Akbar understood Birbal’s point and rewarded the poor man for completing the challenge.
Moral: I Hope can inspire people to work hard.

3. The Foolish Thief :
Once upon a time, a rich merchant was robbed in King Akbar’s kingdom. The grief-stricken merchant went to the court and asked for help. Akbar asked Birbal to help the merchant find, the robber. The merchant told Birbal that he was suspicious of one of his servants. On getting the hint from the merchant, Birbal summoned all the servants and told them to stand in a straight line.

When asked about the robbery, everyone denied doing it, as expected. Birbal then handed over one stick of the same length, to each one of them. While dispersing, Birbal said, “By tomorrow, the robber’s stick will increase by two inches”. The next day when Birbal summoned everyone and inspected their sticks, one servant’s stick was shorter by two inches. On being asked by the merchant about the mystery of finding the real thief, Birbal said, “It was simple: the thief had cut his stick by two inches, fearing that it would increase in size”.

Moral: Truth always prevails.

4. Wise Birbal:
Once upon a time, King Akbar lost a ring that was very precious to him. This ring was a gift from his father and losing it made the king very sad. Akbar summoned Birbal and requested him to find the ring. The court was full of courtiers. Birbal announced, “My great king, the ring is right here in the courtroom, and the one who has the ring has a straw stuck in his beard/’ Everyone started looking at each other, and one of the courtiers started touching his beard to find the straw. Birbal called the guards and asked them to search the suspect. On searching the suspect, the ring was retrieved. Akbar was amazed at how Birbal managed to find the ring. Birbal said, “My King, the one who is guilty will always feel scared”.

Moral: The guilty conscience needs no accusation.

5. The Farmer’s Well:
Once upon a time, a clever man sold his well to a farmer. The next day, when the farmer went to the well to fetch some water, the man said that he only sold the well and not its water. The farmer did not know what to do, and with a sad heart, he went to Akbar’s court. Birbal was told to take care of the case. The following day, the man who sold the well along with the farmer was called to the court. The clever man made the same statement – he had sold his well, not the water in it. On learning this, Birbal said, “My friend, in that case, you either remove your water from the well or pay tax for your water because it is the farmer’s well.” The man realised his mistake and asked for forgiveness as he felt helpless and outwitted.

Moral: If you cheat, you will pay for your deeds.

Question 2.
Collect the letter from library / internet writen by Aurangzeb to his teacher, discuss in the classroom.
Answer:
AURANGAZEB’S LETTER TO HIS TEACHER :
Sir! What do you expect from me? Is there any justification in your asking that I, in my capacity of a famous Muslim ruler, should take you into my court? May be your request would have been reasonable if you had imparted education to me in proper way. A student, who receives good education, should respect his teacher as he respects his father. But, what have you taught me? Firstly, you taught saying that Europe means a small island called Portugal, that the king of that country alone is great, in the next position is the king of Holland and then comes the king of England. You also said the king of the France and Spain are like the petty rulers in our country and that the King of Hindustan are greater than all those Kings, that they are the emperors who conquered the whole world and the kings of Persia, Uzbek, Tartar, China, Eastern China, Pegu, Machina, will shiver at the mere mentioning of the names of Hindustan kings.

Ah! You have taught excellent history and Geography, indeed! Instead, you should have taught me about the different countries in the world and their varied interests, the strengths and weaknesses of those kings, their war strategies, their customs, religions, Government policies, the advantages, History, progress, downfall, what disasters and blunders had led to great changes and revolutions-you should have taught me all these things. I did not learn anything from you regarding the great men, who established the Mughal empire. You did not teach me anything about their life histories. You did not teach about the policies and the strategies that they followed to achieve glorious victories.

You wanted me to learn how to read and write Arabic. You wasted much of my time on something, which cannot be mastered unless I worked hard for ten to twelve years. Perhaps, in your opinion, it is a great thing if a prince becomes a great linguist and a perfect grammarian. May be you thought this esteem is enhanced by learning other languages and foreign languages instead of learning his mother tongue, the language of his people and the languages of neighboring states! Infact, he does not need these languages. Time is quite precious duringthe childhood forthe people like me, who belong to the royal family, since we have to shoulder so many responsibilities. There is an urgent need to learn many things during the limited time that is available to us. You have wasted all my time in teaching Arabic for such a long time, which was boring activity. Study of an Arabic was tragic event in my life. It was useless pursuit. I had to learn it with extreme reluctance. It has even blunted my intellect. (Persian was the official language at that time).

Don’t you knpw that happy childhood memories are preserved forever, that thousands of things can be learned which makes everlasting impression on the young minds and that because of their influence, he can be mentally prepared to take up greater responsibilities? Is it not possible to learn the laws, prayers, and sciences in our mother tongue instead of learning them in Arabic?

I cannot say how long you had taught me that kind of speculative knowledge. I could only remember that those ugly and horrible vocabulary which could surprise and confuse even the most intelligent people. Ignorant egoists like you, who would like to hide their bad qualities, must have created such words. By listening to such bombastic words, we should think that you are knowledgeable and omniscient! We should think that those wonderful words contain some wonderful inner meaning, which could be understood only by scholars like you!

You should have trained me to be a person with analytical thinking. You should have taught me the techniques of being a person of equanimity and imperturbable mind! You should have told me the laws and grandeur of the universe and the fundamental principles of life. You should have filled my mind with this kind of practical philosophy. Had you done these things, I would have shown you same kind of reverence that Alexander showed to his teacher Aristotle. I would have helped you more than that.

Instead of raising me to the skies with flattery, you should have taught me the essentials of being a good king. You should have given me the knowledge of a king’s responsibilities towards his subjects and their responsibilities towards the king. You should have foreseen that a day would came when I should use the sword in the battle with my brother. You should have taught me how to lay siege to a town and rally the soldiers who are scattered in confusion. However, I learned all these things from others, but not from you.

Therefore, now you must go to your village. I will not help you in any manner. Let not the people know who are you. Lead the rest of your life as an ordinary citizen.

Discussion :
Childhood is a good period of learning because a well-taught child remember all the good things taught him then all his life. These things prepare him to be good and noble in life. It is useless to teach a child the law, religion and sciences in a foreign language. A child taught well in his childhood is surely a good and noble man.

Aurangzeb’s last advice to his former tutor is to go back to his village from where he had come to teach him. He tells him to hide himself in a remote village. Nobody should know about his position as a teacher. Nobody should about his position as a teacher. Nobody should also know that he has been censored by the emperor for teaching him in a wrong way. This is some sort of punishment to the bad teacher.

Question 4.
Discuss with your teacher the method of levying agricultural tax during the Mughal period.
Answer:
Land comprised the main tax base, along with a few other taxes including import and export duties, and tributes from states controlled by the Mughals. Indian history
emphasizes the imposition of jizya, a progressive income tax on non-Muslims with an exemption for minimum wagers.

Chauth and Sardeshmukhl

Chauth…’ was 1? 4 of the government revenue paid by Mughal officers.

In addition to this, the sardeshmuki was another ten percent tax.

Previously, the Mughal emperors collected taxes by relying upon a decentralized network of local administrators called zamindars. Acting as local aristocratic landlords, they collected taxes from peasants and sent a set quota to the state. But much of this revenue never made it to the emperor.

Question 5.
Take your favorite story from Akbar – Birbal stories and role play the conversation between Akbar – Birbal in that story with the help of your teacher.
Answer:
The Story of how Birbal came to Akbar’s court Emperor Akbar loved to go hunting. On one such trip, he came across a young man named Mahesh Das. In the meeting that occurred, the Emperor was extremely impressed by the wit of Mahesh Das. The Emperor gave Mahesh Das his ring and asked him to come and visit him in his palace at any time. A few years later Mahesh Das decided to try his luck in the city and to take the emperor up on his offer.

He reached the city of Agra where Emperor Akbar had his fort on the banks of the Yamuna River. At the gate of the fort he was greeted by the guards. He told them that he had come to visit with the emperor. The guards looked at him in disdain (since he was not very well dressed) and asked him why they should let him in. He showed them the ring that was given to him by the emperor as proof.

One of the guards realized that this individual obviously was of importance to the emperor and gave him permission to enter, based on one condition: the young man would share half of what he received from the emperor with the guard. Mahesh Das promised to do so and was given access into the court of Emperor Akbar. He bowed to the emperor as he went in and showed him the ring. The reputedly benevolent Emperor Akbar recognized the ring and the young man and immediately offered him anything he wanted.

The young man thought a while, and asked the emperor for fifty lashes of the whip. The emperor was amazed but he knew that Mahesh Das was a very astute young man and asked him for his reason for his wish. Mahesh Das revealed to the emperor that deal that he had made with the guard outside the fort.

The emperor was thoroughly amused and angry at the same time. He awarded the fifty lashes to the guard for his impertinence and his habit of bullying people. He rewarded Mahesh Das by including him in his court and giving him all the comforts he could desire. He also bestowed on him the name of Birbal.

The building’s longest plane of symmetry runs through the entire complex except for the sarcophagus of Shah Jahan, which is placed off centre in the crypt room below the main floor. This symmetry is extended to the building of an entire mirror mosque in red sandstone, to complement the Mecca-facing mosque placed to the west of the main structure. Parchin kari, a method of decoration on a large scale-inlaid work of jewels and Jali work has been used to decorate the structure.

7th Class Science 8th Lesson Air, Winds and Cyclones Important Questions and Answers

Question 1.
How do you prove that air exerts pressure?
Answer:

  1. We know that a bicycle tube or tube of any other vehicle can burst when it is over filled with air.
  2. Take a balloon and fill it with air. Keep blowing more and more air into it.
  3. The balloon expands and after a point bursts.
  4. The reason for the burst is the increase in air pressure inside them.
  5. For example a balloon being filled with air, the air filled football that becomes hard, water rising through a hand pump, the tubes of cycle, scooter or car are all due to the pressure exerted by air.

AP Board 7th Class Science Important Questions Chapter 8 Air, Winds and Cyclones

Question 2.
How do you show that air exerts pressure by a simple experiment?
Answer:

  1. Take a syringe and draw out its plunger (piston) to the limit.
    AP Board 7th Class Science Important Questions Chapter 8 Air, Winds and Cyclones 1
  2. Close the nozzle of the syringe with a finger and press the piston.
  3. The finger experiences the pressure exerted by air.

Question 3.
What happens on heating air? How is pressure related to this?
Answer:

  1. It is important to remember that on heating the air expands and occupies more space.
  2. When something occupies more space, it becomes less dense.
  3. The warm air is therefore less dense than cold air. Thus smoke and hot air go up.
  4. Similar to observations of activities done so far, numerous factors contribute to heat air.
  5. When the air rises up, air pressure at the place becomes low and we have many kinds of winds as air comes into occupying areas of lower pressure.
  6. The differential heating of land and water by the sun leads to land and sea breeze.

Question 4.
How are land breeze and sea breeze developed?
Answer:

  1. The land heats up faster than the sea, so warm air rises over the land during the day as it is warmed by the Sun.
  2. At certain times of a year, this can create a sea breeze which is a gentle breeze blowing into the land.
    AP Board 7th Class Science Important Questions Chapter 8 Air, Winds and Cyclones 2
  3. At night, the land cools faster than the sea, reversing the air flow.
  4. This creates a land breeze that blows out to sea.

AP Board 7th Class Science Important Questions Chapter 8 Air, Winds and Cyclones

Question 5.
How are we getting monsoon winds? In which months do they come?
Answer:

  1. We have read about the sea breeze and the land breezes.
  2. In summer, near the equator the land heats up faster and during the day the temperature of the land is higher than the water in the ocean.
  3. The air over the land gets heated and rises.
  4. This causes the winds to flow from the oceans towards the land.
  5. These are monsoon winds.
  6. This is usual during the months of June to September.

Question 6.
How are winds useful in our life?
Answer:

  1. The direction of the wind flow gets usually reversed in the months from December to early March.
  2. The wind flows from the land to ocean as the sea cools more slowly.
  3. The winds from the oceans carry water and bring rains.
  4. Farmers in our country depend mainly on rains for their harvests.
  5. We can also generate energy from high-speed wind.
  6. Thus we can see the usefulness of winds in our life.

Question 7.
Describe how cyclones are formed.
Answer:

  1. Tropical cyclones are like giant engines that use warm moist air as fuel.
  2. The warm moist air rises upward from near the surface.
  3. The warm air rises causing an area of lower air pressure below.
    AP Board 7th Class Science Important Questions Chapter 8 Air, Winds and Cyclones 3
  4. Air from surrounding areas of high air pressure pushes into the low pressure area.
  5. Then this “new” air becomes warm and rises too.
  6. As the warm air continues to rise, the surrounding air swirls – into take its place and the water from the sea surface also comes up with the air.
  7. As the warmed moist air rises and cools off, the water in the air forms clouds.
  8. The whole system of clouds and winds spins and grows, fed by the ocean’s heat and water evaporating from the surface. See the figure.
  9. These kinds of satellite images help us to predict the path of the cyclones to some extent.

Question 8.
Write the Do’s and Don ‘ts during cyclones.
Answer:
Cyclones – Do’s and Don’ts:

  1. We should not ignore the warnings issued by the meteorological department through T.V., Radio or newspapers: Pass on the information to others and ignore rumors.
  2. When a cyclone alert is on for your area, continue normal working but stay alert to the radio warnings.
  3. We should make necessary arrangements to shift essential household goods, domestic animals and vehicles, etc. to safer places.
  4. Switch off electrical mains in your house.
  5. Keep ready the phone numbers of all emergency services like police, fire brigade, and medical centres.
  6. Pack essentials for yourself and your family to last few days, including medicines, special food for those who would need it. This may include babies and elders.

AP Board 7th Class Science Important Questions Chapter 8 Air, Winds and Cyclones

Question 9.
Write the precautions to be taken before the cyclone.
Answer:
Precautions to be taken before a cyclone:

  1. We should be cautious about rumours.
  2. If we feel that houses are not safe at the time of cyclone, we have move into a pucca building in the vicinity.
  3. We should keep mobile phones in a waterproof bag, fully charged. If we have more than one mobile phone, we have to use one phone at a time, leaving the other phones switched off and using them one after the other to ensure communication to the longest possible period.
  4. If we have to vacate the house close the toilet seat with sandbags.
  5. We should close the drainage holes to prevent reverse flow of sewage.
  6. The trained students should cooperate with the response teams.
  7. We should make necessary arrangements to shift essential household goods, domestic animals and vehicles, etc. to safer places.

Question 10.
What are the post-cyclone measures?
Answer:
Post cyclone measures :
If you are staying in a cyclone hit area-

  1. Strictly avoid any loose and dangling wires.
  2. Do not drink water that could be contaminated. Always store drinking water for emergencies.
  3. Whenever there is an outbreak of dysentery, we should take tea, decoction and starch solution (Ganji).
  4. We should not go near to bunds of tanks, streams, the river banks, fallen trees, buildings, poles and seashores to play or sight-seeing and taking selfies.
  5. Cooperate and help your neighbours and friends. First aid should be provided to the injured.
  6. At the time of cyclones, some people lose their beloved family members and children or pets. In such situations, we should give assurance, guidance and counselling in order not to go to a depressed state.

Question 11.
Establish the fact that moving air creates low pressure.
Answer:

  1. Take a glass and a postcard.
  2. Keep the glass on a table and the postcard on the glass.
    AP Board 7th Class Science Important Questions Chapter 8 Air, Winds and Cyclones 4
  3. Wave our hand or note book above the postcard to displace the air just above the postcard.
  4. As the card moves, it moves the air there creating low pressure.
  5. Due to this low pressure the card on the glass rises up.
  6. It means moving air creates low pressure.

AP Board 7th Class Science Important Questions Chapter 8 Air, Winds and Cyclones

Question 12.
What are the reasons that different areas have different temperatures? How does this help in getting rain?
Answer:

  1. Uneven heating takes place on the surface of the earth.
  2. We know that regions close to the equator gets more heat from the sun.
  3. This is because of the direction of the sunlight being straighter close to the equator.
  4. The air in these regions gets warmer.
  5. The warm air rises, and the cooler air from the regions in the 0 – 30° latitude belt on either side of the equator moves in.
  6. This movement of air sets forth winds that move over the earth.
  7. We have also seen that the increased wind speed is accompanied by a reduced air pressure and this aids rains.

Question 13.
Do winds cause harm? Explain.
Answer:

  1. We are familiar with the word cyclone.
  2. During the months of May – June or October – November reports about them can be seen in the Newspapers and TV.
  3. This way winds cause harm.

Question 14.
Where do we And air? Explain it with an activity.
Answer:

  1. Take a bucket full of water and transparent glass.
  2. Take a paper, crumple it into a ball and push it to the bottom of the glass.
  3. Invert this glass and immerse it into the bucket of water. Keep the glass straight and press it so that the glass is completely under water.
    AP Board 7th Class Science Important Questions Chapter 8 Air, Winds and Cyclones 5
  4. Take it out and observe what happens.
  5. The paper in the glass did not wet.
  6. However if the glass is tilted air in the glass escapes as bubbles through water and water enters the glass.

Question 15.
Describe a simple activity to show the presence of air.
Answer:

  1. Fill a bucket with water.
  2. Take a bottle with a narrow mouth and immerse it in the bucket till it fills with water.
    AP Board 7th Class Science Important Questions Chapter 8 Air, Winds and Cyclones 6
  3. During the time the bottle is filling with water bubbles of air come out of the glass.
  4. This air is earlier filled in the glass. So the glass is not empty but full of air.
  5. Any bottle, glass or any other container that appears empty is actually full of air.
  6. Nothing can be added to it unless the air inside is removed.
  7. It is only when some air is removed that something else can enter.
  8. Air occupies the space around us.

AP Board 7th Class Science Important Questions Chapter 8 Air, Winds and Cyclones

Question 16.
Show by a simple experiment that air expands on heating.
Answer:

  1. Take an empty injection bottle and one empty ball point refill.
  2. Remove the pin of the refill and insert one of its ends in the cork of the injection bottle as shown in Fig.
  3. Put a water drop on the upper end of the refill.
    AP Board 7th Class Science Important Questions Chapter 8 Air, Winds and Cyclones 7
  4. Rub your hands together so that they become warm.
  5. Carefully pick up the bottle and hold it in both your hands for sometime.
  6. So that the bottle also becomes warm.
  7. The water drop inflate in the refill.
  8. This is because air in the bottle expands due to the heat supplied by the hands.

Question 17.
‘Hot air is lighter than cold air’. How do you prove it?
Answer:

  1. Take two paper bags or empty paper cups of the same size.
  2. Take a broomstick. Hang the two bags in the inverted position on the two ends of the broomstick.
  3. Tie a piece of thread in the middle of the stick. Hold the stick by the thread, like a weighing balance.
    AP Board 7th Class Science Important Questions Chapter 8 Air, Winds and Cyclones 8
  4. Put a burning candle below one of the bags as shown in the figure (b) and observe what happens.
  5. Note that we have used paper bags or cups as they are of a light weight and it would be easier to see the results of this experiment if we take any such light objects to hang on the thread.
  6. The balance of the bags is disturbed.
  7. This proves that hot air is lighter than cold air.

Question 18.
‘Air moves from a region of higher pressure to a lower pressure’. Prove this statement by a simple experiment.
Answer:

  1. Take a balloon. Blow air into it. As we fill it up, it expands and it becomes harder to press the walls of the balloon. The inside air exerts pressure on the walls of the balloon.
  2. Open the mouth of the balloon slightly. Air from the balloon comes out.
  3. We can open the mouth less or more and control the flow of air.
  4. The air in the balloon is at high pressure and it goes towards low pressure area.
  5. We already know that when air moves, it is called wind. Air moves from the region where the air pressure is high to the region where the pressure is low.

AP Board 7th Class Science Important Questions Chapter 8 Air, Winds and Cyclones

Question 19.
How can you demonstrate that warm air rises up?
Answer:

  1. Take an incense stick (agarbati) and light it. Observe the smoke of the incense stick.
  2. When something occupies more space, it becomes less dense. The warm air is therefore less dense than cold air.
  3. The smoke rises up indicating that warm air rises up.

Question 20.
Write an activity to prove that moving air creates low pressure.
Answer:

  1. Wet the edges of glass and put a postcard on it, and hold it inverted with our left hand as shown in figure and move your right hand or note book to move the air form under the paper.
    AP Board 7th Class Science Important Questions Chapter 8 Air, Winds and Cyclones 9
  2. Due to the movement of the hand or note book, air there moves fast.
  3. This moving air creates low pressure and the postcard is pushed out by the air inside the glass.

Question 21.
Prove by an activity that increased wind speed is accompanied by a reduced pressure.
Answer:

  1. Take a glass containing water and two straws. Keep one straw in the water and another in horizontal direction as shown in figure and blow through the horizontal straw.
    AP Board 7th Class Science Important Questions Chapter 8 Air, Winds and Cyclones 10
  2. When you blow over the straw the water comes out due to low pressure which forms inside the straw.
  3. So the water from the glass reaches up in the straw due to high pressure.
  4. We see that the increased wind speed is accompanied by a reduced air pressure.

Question 22.
What is a cyclone? What are the other names for it?

What are the steps needed to use a dropper? Explain its functioning.
AP Board 7th Class Science Important Questions Chapter 8 Air, Winds and Cyclones 11
Answer:
Fig. (a): The air present in the tube of the dropper is removed by pressing the rubber head.
Fig. (b): Putting the open end of the tube of the dropper in water and releasing the pressed rubber head.
Due to low pressure in the tube water enters into it.
Fig. (c): Rubber head is made free from pressing. Water entered in to the tube of the dropper as air there was already sent out.

Question 26.
What is wind?
Answer:

  1. The air around us is rarely still. It moves continuously from one direction to another.
  2. The movement is in many directions.
  3. This is what we call winds.
  4. So we know that wind is moving air.

Question 27.
What are the advantages of advanced technology with regard to cyclones? How do you appreciate it?
Answer:

  1. Advanced Technology has helped and these days we are better protected.
  2. In the early part of last century, coastal residents may have had less than a day to prepare or evacuate their homes from an oncoming cyclone.
  3. The world today is very different.
  4. Thanks to satellites and radars, a cyclone alert or cyclone watch is issued 48 hours in advance of any expected storm and a cyclone warning is issued 24 hours in advance.
  5. The message is broadcast every hour or half an hour when a cyclone is near the coast.

Question 20.
Write a note on the discovery of carbon dioxide.
Answer:

  1. The first step towards trying to find out what air contained was carried out by Von Helmont.
    AP Board 7th Class Science Important Questions Chapter 11 Respiration in Organisms 15
  2. He conducted an experiment of burning charcoal which leads to the formation of ash.
  3. He found the weight of ash to be much less as compared to charcoal.
  4. On the basis of this, he concluded that the decrease in mass was due to the formation of an invisible substance which he named “gas”.
  5. In the year 1756, Joseph Black studied this gas in more detail.
    AP Board 7th Class Science Important Questions Chapter 11 Respiration in Organisms 16
  6. He found that when limestone is heated or reacted with acids, it gives rise to a gas which he called “fixed air”.
  7. He studied several properties of this gas. One of the properties was, lime water turned milky when this gas was passed through it.
  8. Now we know this gas as carbon dioxide.

AP Board 7th Class Science Important Questions Chapter 11 Respiration in Organisms

Question 21.
How is oxygen discovered? Write the history of its discovery.
Answer:

  1. After nearly two decades of discovery of carbon dioxide, oxygen was discovered.
  2. Joseph Priestley, published his“Experiments and observations on different kinds of air” and was the first to prove the different qualities of the gases released by plants and the one’s exhaled by animals (mice).
    AP Board 7th Class Science Important Questions Chapter 11 Respiration in Organisms 17
  3. He discovered that, although a candle burned out in a closed container, when he added a living sprig of mint to the container, the candle would continue to burn.
  4. At the time, Priestley did not know of Oxygen, but he correctly concluded that the mint sprig “restored” the air that the burning candle (or mice which he used in a similar set of experiments) had spoiled.
  5. Priestley shared his observations with Lavoiser.
    AP Board 7th Class Science Important Questions Chapter 11 Respiration in Organisms 18
  6. Lavoiser had also conducted several experiments on atmospheric air and knew that it contained many gases, and he identified Priestley’s discovery as the active component of air for which he had been searching.
  7. He called it oxygen (Greek: acid former), in the belief that all acids contained it.

  3. The ISI mark of a lamp ensures that the appliance is safe.

Question 7.
What is an electric fuse? Explain its importance. How does it work?
Answer:
Electric Fuses:

  1. When excessive electric current flows through a circuit the wires or the appliances may get heated and can catch fire.
  2. To avoid fire, a safety device known as a fuse is connected in series in the circuit.
  3. A fuse is a small piece of wire as shown in figure.
    AP Board 7th Class Science Important Questions Chapter 7 Electricity – Current and Its Effect 9
  4. It is made of a special alloy that gets heated quickly and melts.
  5. If the current in the circuit is too high, the fuse wire gets hot and melts.
  6. This leaves a gap in the circuit. Automatically the circuit is broken and flow of electricity is stopped.
  7. This protects appliances from getting burnt due to the passage of too large a current through them.

AP Board 7th Class Science Important Questions Chapter 7 Electricity – Current and Its Effect

Question 8.
What is a Miniature Circuit Breaker (MCB)? What is its advantage? For which mark should we look at it?
Answer:
Miniature Circuit Breaker (MCB):

  1. These days Miniature Circuit Breaker (MCB) is increasingly being used in place of fuses.
  2. These are switches which automatically turn off when current in a circuit exceeds the safe limit.
  3. It has a switch which goes OFF automatically if there is overheating.
    AP Board 7th Class Science Important Questions Chapter 7 Electricity – Current and Its Effect 10
  4. This breaks the circuit. If we turn them on, the circuit is once Miniature Circuit again complete.
  5. The advantage miniature circuit breakers have over fuses is that they can be reset (manually or automatically) to restore normal operation, whereas fuses need to be replaced after every single operation.
  6. The MCB can be reset by hand and the circuit becomes complete once again.
  7. Look for ISI mark on MCBs.

Question 9.
What are the inventions of Michael Faraday?
Answer:
Michael Faraday (1791-1867): Michael Faraday observed that by moving a magnet in and out of a coil we can make electric current flow through the coil. Using this he built the first electric generator or dynamo in 1831. He also invented the transformer.

Please do follow my suggestions.

  1. Cross the road at the Zebra Crossing….
  2. Do not run on the streets. …
  3. Always walk on the pavement….
  4. Do not stick your hand or head out of a moving vehicle. …
  5. Strap on seatbelts in cars. …
  6. Get off on the safer side of the car….
  7. Gear up for bicycle rides.

Wish you a bright future

Thank you raa.

Question 2.
Have you visited any historical places earlier? Try to write a travelogue.
Answer:
Yes, I visited important historical places, Madurai, Rameswaram in Tamilnadu.

Like a lot of other trips, Madurai to Kanyakumari circuit had been on my mind for a long time. Since the whole trip was not working out I went for a short trip to Madhurai and Rameshwaram.

I went on road way. The road from Madurai is single lane but very good and does not have too much traffic like NH.7.

I stayed at a Hotel. It provide all facilities.

About Madurai:
I saw Meenakshi temple is what makes Madurai famous.

Temple is located at the middle of the city. I can enter the temple from all four directions, but east is the recommend direction to enter.

As I go inside by design I get into the queue for darshan. And came out only after I have had the darshan.

When I came after the Sundareswar darshan from the exit on the eastern side, i came across the Mandapam or hall with thousand pillars. The central hall has Nataraj Statue.

Next I went to Rameswaram Temple.

This temple is similar to the Madurai Meenakshi temple, may be a bit smaller. The unique feature of this temple is the 22 wells. The temple has many Shiva Lingas.

I returned after 3 days. I am so tired, but I am happy I did it.

AP State Syllabus 7th Class Science Important Questions 4th Lesson Motion and Time

7th Class Science 4th Lesson Motion and Time Important Questions and Answers

Question 1.
Give few examples of motion you observe in day to day life.
Answer:

  1. Motion is a common experience in our life. We observe birds flying in air, buses, autos, cars, bullock carts, moving on roads, trains on railway tracks and many other objects around us in motion.
  2. Apart from observing motions of objects around us, we ourselves experience motion while we are walking, running, playing, riding a bicycle etc.
  3. Similarly, we observe many objects like trees, buildings, display boards, electric poles etc., at rest while we walk to school.

AP Board 7th Class Science Important Questions Chapter 4 Motion and Time

Question 2.
How do you explain the terms motion and rest? Give an illustrative answer.
Answer:

  1. We know that the position of the car has changed with respect to the tree in ‘2’ seconds. But there is no change in the position of the tree with respect to its surroundings.
    AP Board 7th Class Science Important Questions Chapter 4 Motion and Time 1
  2. An object is said to be in motion if it changes its position with respect to its surroundings in a given time.
  3. An object is said to be at rest if there is no change in its position with respect to its surroundings in a given time.
  4. Thus, we can say that the tree is at rest and the car is in motion while we observe them over a period of time (2 seconds in this case).

Question 3.
Explain the terms uniform and non-uniform motions and define them.
Answer:
Uniform and non-uniform motion:

  1. A body is said to be in motion if its position keeps on changing with time (with respect to the observer).
  2. But in our daily life we experience certain motions in which, the change in position of objects remains the same for a time interval, in some other motions, the change in position of the object will not be the same for a given time interval.
  3. Uniform motion (Definition): If a body covers equal distances in equal intervals of time it is said to be in uniform motion.
  4. Non – Uniform motion (Definition): If a body covers unequal distances in equal intervals of time, it is said to be in non – uniform motion.

AP Board 7th Class Science Important Questions Chapter 4 Motion and Time

Question 4.
Explain the types of motion with suitable examples.

  3. A car travelling along a straight road.
  4. Motion of blades of a ceiling fan.
  5. Motion of needle in a running sewing machine.
  6. Motion of pendulum in an old wall clock.
  7. Considering the direction of motion what differences do we notice in above examples?
  8. The motions in the above examples are different in terms of direction of motion.
    a) Car is moving in same direction along a straight line.
    AP Board 7th Class Science Important Questions Chapter 4 Motion and Time 2
    b) Blades of ceiling fan rotate about a fixed line in a circular path.
    AP Board 7th Class Science Important Questions Chapter 4 Motion and Time 3
    c) Needle of sewing machine moves up and down about a fixed point.
    AP Board 7th Class Science Important Questions Chapter 4 Motion and Time 4
    d) Pendulum of the wall clock oscillates ‘to’ and ‘fro’ about a fixed point.
    AP Board 7th Class Science Important Questions Chapter 4 Motion and Time 5
  9. Based on the path taken by the bodies in motion we classify motion of bodies as,
    1) Translatory motion
    2) Rotatory motion
    3) Oscillatory motion

Question 5.
Define rectilinear motion and curvilinear motion.
Answer:

  1. Rectilinear motion (Definition): If a body in translatory motion moves along a straight line then motion is called rectilinear motion.
  2. Curvilinear motion (Definition): If a body in translatory motion moves along a curved path then motion is called curvilinear motion.

AP Board 7th Class Science Important Questions Chapter 4 Motion and Time 6
AP Board 7th Class Science Important Questions Chapter 4 Motion and Time 7
1. What similarity do we find in all the motions?
Answer:
We find all the bodies rotating around an axis.

2. What is the path of motion of each particle of the body that moves?
Answer:
The path of motion of each particle of the body that moves is circular.

3. Is there any change in the position of a body while it is in motion?
Answer:
Except car there is no change in the position of the bodies while they are in motion.
The motion of all these bodies is rotatory motion.

AP Board 7th Class Science Important Questions Chapter 4 Motion and Time

Question 8.
Explain rotatory motion by taking the blades of a fan moving as an example. Define rotatory motion.
Answer:

  1. While the blade of a fan is moving, the points A, B, and C on the blade move to Av Br Cj first and then move to A2, B, and C2 position,
  2. Thus when a fan is in motion, each point on the blade moves in a circular path around the centre of the fan which is fixed.
  3. Here, we observe that the position of a fan is not changing.
    Only the blades of fan are changing their position continuously and moving in circular path around a fixed point.
    AP Board 7th Class Science Important Questions Chapter 4 Motion and Time 8
  4. The imaginary line passing through this fixed point is called axis of rotation.
  5. This type of motion is called Rotatory Motion.
  6. Rotatory motion (Definition) : Rotatory motion means that, motion of all particles of a moving body follow a circular path with respect to a fixed centre or axis of rotation.

Question 9.
Explain the terms ‘slow’ and ‘fast motions’.
Answer:

  1. We observe many objects in motion in our daily life.
  2. In some cases objects move slowly and in other cases they move fast.
  3. To know whether the motion is slow or fast

Let us assume that you started to school on a bicycle and your friend started in a bus at the same time from a place.
a) Who reaches the school first? Why?
b) Do you find any difference in the time taken by bicycle and bus to reach the school?

Question 14.
What is the need to know the speed? How do we know it?
Answer:

  1. Many objects in the world around us are moving.
  2. To compare how fast they are moving, we need to know their speed.
  3. You may have observed the speedometer in motor cars which tells us how fast the car is travelling.
  4. Usually, the speedometer in a vehicle shows the distance travelled in kilometers and the needle shows the speed of the journey in kilometers per hour.
  5. Look at the speedometers of two vehicles shown here and decide which vehicle is slower.
    Car – 1 is slower.
    AP Board 7th Class Science Important Questions Chapter 4 Motion and Time 11

Question 15.
How do you calculate the average speed of any object?
Answer:

  1. Average speed = Total distance travelled / Total time taken to travel the distance.
  2. Thus we can define speed of an object as the distance travelled by it in a unit of time.

Question 16.
What are the units of speed?
Answer:
Units of speed.

  1. Depending on the need and context, speed is measured in different units.
  2. Unit of speed in S.I. system is meter per second (m/s)

Question 19.
Consider a car driven on a road. A person seated beside the driver recorded the distance travelled after every 10 minutes by noting the distance reading in the
speedometer. The distance travelled by the car at different instances of time is as follow.
a) What is the total distance travelled by the car?
b) What is the time taken to travel the distance?

Time Reading of Distance Covered
0 minute 0 km
10 minute 15 km
20 minute 25 km
30 minute 38 km
40 minute 60 km

c) How do you find the speed of the car?
d) Is the speed of the car uniform throughout the journey?
Answer:
a) Total distance travelled by the car = 60 km.
b) Time taken = 40 min.
c) To find the speed of the car in the journey we should calculate total distance travelled by the car and the total time taken to cover that distance.
Total distance travelled by the car = 60 km
Time taken = 40 min.
The distance must be either in meters or kilometers and time in seconds or hours. We express the speed either in m/s or in km/h. In this example distance is 60 km and time is 40 min.
1 hour = 60 min
AP Board 7th Class Science Important Questions Chapter 4 Motion and Time 12
Thus, the car travelled with an average speed of 90 km/h.
d) From the table, we notice that the car has covered unequal distances in equal intervals of time (10 min), which shows the speed of the car is not uniform.

Question 20.
The speed of a bus is 72 km/h, whereas the speed of a car is 12.5 m/s. Which vehicle moves faster?
Answer:
1) The speed of the bus is = 72 km/h
= 72 × \(\frac{5}{18}\) = 20 m/s
2) The speed of the car is = 12.5 m/s
3) As the speed of the bus is more than the speed of the car, the bus moves faster.
Note: To compare two speeds. They must be expressed in the same units. In the above example, speed of a bus is expressed in km/h and the speed of a car in m/s, tp compare these speeds, one of them must be converted to other.
Speed of a bus = 72 km/h = 20 m/s

AP Board 7th Class Science Important Questions Chapter 4 Motion and Time

Question 21.
How can you prove that motion is relative to the observer?
Answer:
Observing motion of the car.
Look at the pictures.

  1. Imagine that you sat in the moving car beside the driver.
  2. As the car moves, the distance between you and the landmarks like buildings, trees, poles etc., outside the car changes.
  3. This change in the scene you view through the window indicates that the car is moving.
  4. However your position with respect to the driver of the car remains the same.
  5. That is you and the driver of the car are at rest with respect to each other, but both of you are in motion with respect to the surroundings outside the car.
  6. A body may be at rest with respect to one set of surroundings and at the same time be in motion with respect to another set of the surroundings.
    Thus motion is relative to the observer.

Question 25.
Observe the following tables, showing distances travelled by two different cars for different instances of time.
AP Board 7th Class Science Important Questions Chapter 4 Motion and Time 18
1) Which car has travelled equal distances in equal intervals of time?
2) Which car has travelled unequal distances in equal intervals of time?
Answer:

  1. Obviously we notice that for car – A, the change in position in every 10 seconds is 150 m. But for car – B, the change in position is not constant.
  2. For 1st 10 seconds, it is 50 m, for 2nd 10 seconds, it is 40 m, for 3rd 10 seconds it is 90 m, and for 4th 10 seconds it is 50 m.

Question 28.
Take a table tennis ball, and keep it on the surface of a table. Push the ball with your finger and observe its motion. Is it in Rotatory motion or in Translatory motion?
Answer:

  1. When you push the ball on the surface of a table, it moves from one end to the other end and all the particles of the ball also move along the direction of motion of the ball.
    AP Board 7th Class Science Important Questions Chapter 4 Motion and Time 20
  2. Hence the balls is in translatory motion.
  3. Similarly, each particle of the ball moves in a circular path about a particular line, when the ball rolls on the surface.

Question 38.
How do we measure or estimate time? Explain with an example.
Answer:

  1. Ravi and Sathish started for school at 8.00 a.m. from their houses which are side by side. Ravi started on a bicycle and Sathish by walk.
    • Who will reach the school first? How much earlier will he be compared to the other?
    • How do you measure ‘early’ or ‘late’ arrival at school?
      AP Board 7th Class Science Important Questions Chapter 4 Motion and Time 28
  2. You can easily estimate that Ravi reaches the school earlier than Sathish.
  3. But to answer the question of how early Ravi reached, we need to measure the times taken by both Ravi and Sathish and find the difference of time between both the cases.
  4. For this we need time measuring instruments like watches, clocks etc.
  5. Nowadays, we use different instruments like electronic clocks, digital clocks, quartz clocks etc. to measure time.
