Amount of energy received in unit time on a unit area perpendicular to the sun's
Answers
The amount of energy received in unit time on a unit area perpendicular to the sun's direction at the mean distance of the earth from the sun is called solar radiation. It is defined as the solar energy receivingat the top of the atmosphere, denoted by Isc.

Answer:
The amount of energy received by the earth is 4.33× 10⁻¹² Joules in unit time and 1.34 KW energy on a unit area perpendicular to the sun.
Explanation:
The energy is produced in the sun by the nuclear fusion of hydrogen atoms. The nuclear fusion reaction takes place inside the core of the sun. The conditions required for the sun to release solar energy are:
- Presence of a sufficient amount of hydrogen.
- High temperature to produce free hydrogen atoms.
- High pressure to bring hydrogen proton closer for reaction.
The nuclear fusion reaction takes place inside the core of the sun.
The high temperature produces hydrogen atoms to form hydrogen nuclei and then the high pressure brings hydrogen protons together to form helium nuclei as the product of the nuclear fusion reaction.
During this process, some masses change into energy which is released in the form of heat and light energy as solar energy received by the earth.
Thus, the sun is able to release a very high amount of energy every second and the earth is able to receive it continuously.
