In this problem you will consider the balance of thermal energy radiated and absorbed by a person.
Assume that the person is wearing only a skimpy bathing suit of negligible area. As a rough approximation, the area of a human body may be considered to be that of the sides of a cylinder of length L=2.0m and circumference C=0.8m.
For the Stefan-Boltzmann constant use ?=5.67A????110?8W/m2/K4.
Find Pnet, the net power radiated by the person when in a room with temperature Troom=20?C.
Express the net radiated power numerically, to the nearest 10 W.
