The Earth has a surface temperature around 270 K and an emissivity of 0.8, while space has a temperature of around 2 K. Use Stefan\'s law: P(net) = 5.67×10-8 W/K4 m2 *A*e*(T4 - To4) to solve the following questions. (Radii of the Earth and the Sun are Re = 6.38×106 m, Rs = 7×108 m.)

If the Earth is in thermal equilibrium, how much power must the Earth absorb from the Sun?
