3. (10 points) Radiation from the Sun reaching Earth (just outside the atmosphere) has an intensity of 1.37 kW/mthe distance from the earth to the Sun is 1 AU (1 AU = 1.496 * 10km, where AU is the average distance from the Earth to the Sun). (a) At what rate is the energy produced by the Sun (the power of the Sun)? Assuming that Earth (and its atmosphere) behaves like a flat disk perpendicular to the Sun's rays and that all the incident energy is absorbed, find (b) the power received by the Earth from the Sun (Earth radius = 6.37 10km) (c) calculate the force on Earth due to radiation pressure. (d) What is the intensity of the radiation from the Sun at the surface of Pluto (Pluto is 39 AU from the Sun). (e) calculate the force on Pluto due to radiation pressure (Pluto radius = 1.188 x 10km). x OCSI At a distance of 1 AU from the Sun, this square meter of area receives 1370 watts of light power from the Sun. of sight powe Close up of this square meter of area 1 AU ter
