JK Bank Physics Problems With Answer-Monk Test 2020

#1. Radiocarbon is produced in the atmosphere as a result of

collision between fast neutrons and nitrogen nuclei present in the atmosphere

action of ultraviolet light from the sun on atmospheric oxygen

action of solar radiations particularly cosmic rays on carbon dioxide present in the atmosphere

Answer: Option A

#2. It is easier to roll a stone up a sloping road than to lift it vertical upwards because

work done in rolling is more than in lifting

work done in lifting the stone is equal to rolling it

work done in both is same but the rate of doing work is less in rolling

work done in rolling a stone is less than in lifting it

Answer: Option D

#3. The absorption of ink by blotting paper involves

viscosity of ink

capillary action phenomenon

diffusion of ink through the blotting

siphon action

Answer: Option B

#4. Siphon will fail to work if

the densities of the liquid in the two vessels are equal

the level of the liquid in the two vessels are at the same height

both its limbs are of unequal length

the temperature of the liquids in the two vessels are the same

Answer: Option B

#5. Large transformers, when used for some time, become very hot and are cooled by circulating oil. The heating of the transformer is due to

the heating effect of current alone

hysteresis loss alone

both the heating effect of current and hysteresis loss

intense sunlight at noon

Answer: Option C

#6. Nuclear sizes are expressed in a unit named

Fermi

angstrom

newton

tesla

Answer: Option A

Explanation:

Fermi – A unit of length equal to 10^-15 meter (one femtometer), used in nuclear physics. It is similar to the diameter of a proton.

#7. Light year is a unit of

time

distance

light

intensity of light

Answer: Option B

#8. Mirage is due to

unequal heating of different parts of the atmosphere

magnetic disturbances in the atmosphere

depletion of ozone layer in the atmosphere

equal heating of different parts of the atmosphere

Answer: Option A

#9. Light from the Sun reaches us in nearly

2 minutes

4 minutes

8 minutes

16 minutes

Answer: Option C

#10. Stars appears to move from east to west because

all stars move from east to west

the earth rotates from west to east

the earth rotates from east to west

the background of the stars moves from west to east

Answer: Option B

#11. Stars appears to move from east to west because

all stars move from east to west

the earth rotates from west to east

the earth rotates from east to west

the background of the stars moves from west to east

Answer: Option B

#12. Pa(Pascal) is the unit for

thrust

pressure

frequency

conductivity

Answer: Option B

#13. Planets do not twinkle because

they emit light of a constant intensity

their distance from the earth does not change with time

they are very far away from the earth resulting in decrease in intensity of light

they are nearer to earth and hence we receive a greater amount of light and, therefore minor variations in the intensity are not noticeable

Answer: Option D

#14. Metals are good conductors of electricity because

they contain free electrons

the atoms are lightly packed

they have high melting point

All of the above

Answer: Option A

#15. Let a thin capillary tube be replaced with another tube of insufficient length then, we find water

will overflow

will not rise

depressed

change its meniscus

Answer: Option B

#16. Out of the following pairs, choose the pair in which the physical quantities do not have identical dimension?

Pressure and Young's modules

Planck's constant and Angular momentum

Impulse and moment of force

Force and rate of change of linear momentum

Answer: Option C

#17. If two bodies of different masses, initially at rest, are acted upon by the same force for the same time, then the both bodies acquire the same

velocity

momentum

acceleration

kinetic energy

Answer: Option B

#18. Pick out the scalar quantity

force

pressure

velocity

acceleration

Answer: Option B

#19. Rectifiers are used to convert

Direct current to Alternating current

Alternating current to Direct current

high voltage to low voltage

low voltage to high voltage

Answer: Option B

#20. out of the following, which is not emitted by radioactive substance?

Electrons

Electromagnetic radiations

Alpha particles

Neutrons

Answer: Option D

#21. Sound waves in air are

transverse

longitudinal

electromagnetic

polarised

Answer: Option B
