Answer:
Explanation:
The intensity falling over a surface area is defined as Energy falling per unit area per unit volume, i.e,
I = [tex]\frac{Energy}{Area\times Time }[/tex]
Also, Power, P = Energy/time
So, Intensity = Power/ Area
or, Power = Intensity × Area
Now, Distance from Sun to Earth , r = 149.6 × [tex]10^{9}[/tex] m
So, Surface area of the sphere of radius r will be:-
A = 4 π [tex]r^{2}[/tex]
= 4 × 3.14 × (149.6 × [tex]10^{9}[/tex])²
= 2.81 × [tex]10^{23}[/tex] m²
Thus Average Power will be:
P = 1350 × 2.81 × [tex]10^{23}[/tex]
= 3.7935 × [tex]10^{26}[/tex]
= 3.8 × [tex]10^{26}[/tex] W
