Answer 1

Answer:

This is physics question not from biology

Answer 2

Answer:

Explanation:

Stefan's Law states that the radiated power density (W/m2) of a black body is proportional to its absolute temperature T raised to the fourth power. The emissivity e is a correction for an approximate black body radiator, where e = 1 – R, is the fraction of the light reflected (R) by the black body.
