The intensity of sunlight striking Earth's upper atmosphere is approximately \(1.35 \times 10^{3} \mathrm{~W} / \mathrm{m}^{2}\).

(a) Calculate \(E_{\text {max }}\) and \(B_{\max }\) at this location.

(b) Given that Earth is \(1.5 \times 10^{11} \mathrm{~m}\) from the Sun, what is the power output of the Sun?

(c) If all the sunlight that strikes the upper atmosphere reached Earth's surface, how many watts of power would reach Earth's surface? (Hint: The EarthSun distance is so great that you can assume all the sunlight is perpendicular to the cross section of Earth.)
