Answer 2

Answer:

Explanation:

1)Solar constant, the total radiation energy received from the Sun per unit of time per unit of area on a theoretical surface perpendicular to the Sun’s rays and at Earth’s mean distance from the Sun.

2)It is most accurately measured from satellites where atmospheric effects are absent.

3)The value of the constant is approximately 1.366 kilowatts per square meter.

4)The “constant” is fairly constant, increasing by only 0.2 percent at the peak of each 11-year solar cycle.
