Solve the all parts of given problem:
Problem: The example showed that the Sun emits energy at the rate of about 3.9 x 1026 W.
Part A) Using astronomical data in appendix E, estimate the fraction of this energy that falls on Earth.
Part B) With the Sun directly overhead, what's the rate at which energy strikes each square meter of Earth's surface?
Part C) Discuss the implications of your answer in part (B) for solar energy use.
Explain each step in detail and ignore reflection and absorption by the atmosphere.
