Why does moon have very cold and very hot temperature variations eg, from -190°C to 110°C even though it is at the same distance from the sun as the earth is?
There is absence of atmosphere on the moon,so no part of heat remains trapped in its atmosphere. That is why in day time moon gets hot and in night it cools down and cools fast and all heat is radiated off into the space there by making variation of moon’s surface temperature extreme.
The productivity of a plant is measured by the rate at which it photosynthesises. The amount of carbon dioxide present in a plant is directly proportional to the rate of...
Infra-red radiations in sunlight pass through the glass and heat the interior of the car. The radiation emitted by upholstery and other inner parts of the car cannot pass out...
The Earth and the moon experience equal gravitational forces from each other. However, the mass of the Earth is much larger than the mass of the moon. Hence, it accelerates...
When the moon or the sun is observed through a thin layer of the high clouds, a reflection of light from fine icy crystals, present in the clouds, results in...
(i) The Balkan was a region of geographical and ethnic variation comprising of many states and territories whose inhabitants were commonly known as Slaves.

Tidal effect depends inversely upon the cube of the distance while, gravitational force depends inversely on the square of the distance. Since the distance between the Moon and the Earth is...
(b) 0.0027 m/s2
Explanation:
When moving in the orbit, the moon balances the force on it by the earth with its uniform circular motion in the orbit resulting in centrifugal force. When...
