The mean distance between the Earth and the Sun is 1.50
The mean distance between the Earth and the Sun is 1.50
Solutions
Expert Solution
Given :
.
Intensity (I) = 1390 W /m2
.
Distance
(r) = 1.50 
1011
m
.
We know that :
.
Power (P) = Intensity * Surface area
.
= I * 4?r2 ( surface area ofsphere )
.
=
1390 W /m2 * 4 * 3.14 * (1.501011
)2
.
= ----------- W
