Answer 1

Earth receives 1 part out of 20,00,00,000 parts of solar radiation.

Explanation:

Earth receives only 1 part out of 2,00,00,00,000 (2 billion) parts of the solar radiation emitted by the Sun. This is considered an optimum amount of energy necessary to sustain life and various processes on Earth. The Sun emits an enormous amount of energy, but only a very small fraction of it reaches our planet due to the vast distances involved and the dispersion of solar radiation in space.
