Question
The average energy flow of sunlight arriving perpendicular to the Earth is known as the solar constant and its value is approximately 1300 W/m. a) If sunlight is absorbed entirely by the surface of the Earth, what is the pressure exerted on it? b) And if the Earth perfectly reflected the radiation, what would be the pressure exerted on the surface in that case? c) Are these pressures comparable to atmospheric pressure?
