General Science

1. How the necessary centripetal force is provided in the case Of artificial satellites orbiting around the earth ?

a. It is provided by the engine of the artificial satellite.

b. It is provided by the gravitational attraction between the earth and the satellite.

c. It is provided by the gravitational attraction between the MOOn and the satellite.

d. It is provided by means of a remote control systern.

2. How does, saft straw work?

a. When air is sucked, a low pressure is created inside the straw. But pressure outside the straw remains high. This differenct in pressure forces the soda upwards.

b. When air is sucked, the force of adhesion between the soda and. straw is reduced. Due to this reduction in the magnitude of the adhesive force, the soda rises in the straw.

c. When air is sucked, eddy currents are produced inside the straw. These eddy currents force the soda to rise upwards.

d. All of these.

3. Weigbt of a body is maximum at

a. the surface of the earth.

b. the centre of the earth.

c. an altitude of 500 kms.

d. a depth of 50 kms.

4. The force of attraction between any two bodies in this universe is known as

a. force of gravity.

b. force of gravitation.

c. centripetal force.

d. centrifugal force.

5. How a boatman should row if he wants to take his boat to a poim*t just opposite on the other bank of the river ?

a. He should row straight towards that point.

b. He should row in a direction inclined to the bank up-stream.

c. In whatever way he may row, he cannot reach that point.

d. None of these.

6. Which of the following is the Newton's law of motion?

a. Every body continues in its state of rest or of uniform motion in a straight line unless it is compelled by external forces to change that state.

b. The rate of change of momentum of a body is directly proportional to the impressed force and takes place in the direction of the force.

c. To every action, there is an equal and opposite reaction.

d. All of these.

7. Which of the following changes can be brought about by the, application of a force ?

a. Change in the state of rest of a body.

b. Change in the state of motion of a body.

c. Both of these.

d. None of these.

8. Why a passenger standing in a bus falls backward when'the bus is suddenly set in motion ?

a. Because action and reaction are equal and opposite.

b. Because, in this case, the action becomes greater than the reaction.

c. Because, in this case, the reaction is greater than the action.

d. Because the lower part of the body begins to move along with the bus while the upper part (of the body) tends to remain at rest due to inertia of rest.

9. Which of the following is due to capillary action ?

a. A blotting paper absorbs ink.

b. Oil rises in the wicks, to the flame.

c. Both of these.

d. None of these.

10. Why a cyclist bends slightly inwards when taking a turn ?

a. Because it provides him the centripetal force necessary to keep him stable.

b. Because he wants to have a better view of the traffic ahead.

c. Both of these.

d. None of these.

Crazy Facts About The Universe

Saturn floats

As big as the planet Saturn is, if you were to put it in a glass of water, it would float. This is because its density is .687 grams per cm cubed while waters is the famous .998 g per cm cubed. Unfortunately though, you would need a glass that is over 120,000 km in diameter to witness this.
