Chapter 34, Problem 42

(choose chapter or problem)

Assume the intensity of solar radiation incident on the upper atmosphere of the Earth is 1 \(370 \mathrm{~W} / \mathrm{m}^{2}\) and use data from Table 13.2 as necessary. Determine (a) the intensity of solar radiation incident on Mars, (b) the total power incident on Mars, and (c) the radiation force that acts on that planet if it absorbs nearly all the light. (d) State how this force compares with the gravitational attraction exerted by the Sun on Mars. (e) Compare the ratio of the gravitational force to the light-pressure force exerted on the Earth and the ratio of these forces exerted on Mars, found in part (d).
