Question

Amount of solar energy received from the sun each year is

• A. $20\times {10}^{5}k.cals$
• B. $5\times {20}^{10}k.cals$
• C. $5\times {10}^{30}k.cals$
• D. $5\times {10}^{20}k.cals$

Answer 1

Answer: (D)

$5\times {10}^{20}k.cals$

• The sun is considered as the major source of energy. The solar energy is the renewable form of energy and is used for various purposes like generating electricity, working of the solar batteries, etc.
• The total amount of the energy which is received by the Earth from the sun is equal to about 15×10${}^{20}$ kcal.
• The amount of solar energy which is received every year is about 5×10${}^{20}$ kcal.
• Thus, the correct answer is option D.
