4. As noted in the preceding example, the Sun delivers about 1 000 W/m² of energy to the Earth's surface via electromagnetic radiation. (a) Calculate the total power that is incident on a roof of dimensions 8.00 m ×20.0 m. (b) Determine the radiation pressure and the radiation force exerted on the roof, assuming that the roof covering is a perfect absorber.
