Explanation:
Detailed explanation-1: -Surface temperature: 10, 000 degrees Fahrenheit. Composition: Hydrogen, helium.
Detailed explanation-2: -Every one second, P joules of energy are radiated from the surface of the sun and this energy passes through the surface of a sphere of radius D centered at the sun. The energy passing through a unit area per second = P/4D2 = 1.4 * 103 Wm-2. Therefore P = 4(1.5 * 1011)2 * (1.4 * 103) W = 3.96 * 1026 W.
Detailed explanation-3: -The radiation emitted by the Earth’s surface at 300K is 459.27 Wm − 2 .
