G.K. Practice Test: Question Set - 01

1. Stars appears to move from east to west because
    (A) All stars move from east to west
    (B) The earth rotates from west to east
    (C) The earth rotates from east to west
    (D) The background of the stars moves from west to east

2. Let a thin capillary tube be replaced with another tube of insufficient length then, we find water
    (A) Will overflow
    (B) Will not rise
    (C) Depressed
    (D) Change its meniscus

3. Rectifiers are used to convert
    (A) Direct current to Alternating current
    (B) Alternating current to Direct current
    (C) High voltage to low voltage
    (D) Low voltage to high voltage

4. Magnetism at the center of a bar magnet is
    (A) Minimum
    (B) Maximum
    (C) Zero
    (D) Minimum or maximum

5. Point ‘A’ is at a lower electrical potential than point ‘B’. An electron between them on the line joining them will
    (A) Move towards A
    (B) Move towards B
    (C) Move at right angles to the line joining A and B
    (D) Remain at rest

6. It takes much longer to cook food in the hills than in the plains, because
    (A) In the hills the atmospheric pressure is lower than that in the plains and therefore water boils at a temperature lower than 100°C causing an increase in cooking time
    (B) Due to low atmospheric pressure on the hills, the water boils at a temperature higher than 100°C and therefore water takes longer to boil
    (C) In the hills the atmospheric density is low and therefore a lot of heat is lost to the atmosphere
    (D) In the hills the humidity is high and therefore a lot of heat is absorbed by the atmosphere leaving very little heat for cooking

7. Oil raise up the wick in a lamp. The principle involves
    (A) The diffusion of oil through the wick
    (B) The liquid state of oil
    (C) Capillary action phenomenon
    (D) Volatility of oil

8. Intensity of sound at a point is __________ its distance from the source.
    (A) Directly proportional to
    (B) Inversely proportional to
    (C) Directly proportional to square of
    (D) Inversely proportional to square of

9. Out of the following pairs, which one does not have identical dimension?
    (A) Moment of inertia and moment of a force
    (B) Work and Torque
    (C) Angular momentum and Planck's constant
    (D) Impulse and Momentum

10. On a stationary sail boat, air is blown from a fan attached to the boat. The boat
    (A) Moves in opposite direction in which the air is blown
    (B) Does not move
    (C) Moves in the same direction in which air blows
    (D) Spins around
