Attraction among the Planets and the Sun

Attraction among the Planets

15 / 25

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

intense sunlight at noon

both the heating effect of current and hysteresis loss

hysteresis loss alone

16 / 25

the earth rotates from east to west

the earth rotates from west to east

all stars move from east to west

the background of the stars moves from west to east

17 / 25

Color of the rainbow

Color in the spectrum of the white light

color found in nature

colors which cannot be produced

22 / 25

Sun and the other stars are virtuously huge nuclear explosion chambers producing a large amount of head and light yet, we do not hear any of the explosions because A. Heat and light are electromagnetic:

the outer space is an absolute vacuum

the process involved in the interior of the sun and the starts relate to atomic and subatomic particles and not molecules and their vibration

Sound waves get attenuated completely before they reach the earth

Heat and light are electromagnetic

23 / 25

Siphon will fail to work if:

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

the densities of the liquid in the two vessels are equal

both its limbs are of unequal length

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

24 / 25

Mirage is due to:

depletion of ozone layer in the atmosphere

unequal heating of different parts of the atmosphere

magnetic disturbances in the atmosphere

equal heating of different parts of the atmosphere

25 / 25

Planets do not twinkle because:

their distance from the earth does not change with time

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

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

they emit light of a constant intensity
