If the sun is about 150 Gm away from the Earth, what is the total power that hits the earth? You may assume that the Earth is a disk that faces the sun with a radius of 6378 km and the area is that of a circle of the same radius. (Answer in PW = 1e15 W with three sig figs)

Calculate the average power that the surface of Earth facing the Sun receives from the Sun. Assuming that the Earth is a blackbody and radiates the same amount of power that it absorbs from the Sun, calculate the average surface temperature of the Earth. Does your answer make sense compared to your experience? The Sun’s surface temperature is 5800 K, its radius is 6.96x108 m, the distance between Earth and the Sun is 1.5x1011 m, and the radius of the...

The average temperature of the surface of the Earth is approximately 14◦C. What would the steady-state temperature of the Earth be if there were no greenhouse effect — i.e. if the emissivity of the earth was independent of wavelength? Give your answer in ◦C.
