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 σ=5.67×10^−8w/m^2/k4. a. if the surface temperature of the skin is taken to be tbody=30∘c, how much thermal power prb does the body described in the introduction radiate? take the emissivity to be e=0.6. express the power radiated into the room by the body numerically, rounded to the nearest 10 w. b. the basal metabolism of a human adult is the total rate of energy production when a person is not performing significant physical activity. it has a value around 125 w, most of which is lost by heat conduction to the surrounding air and especially to the exhaled air that was warmed while inside the lungs. given this energy production rate, it would seem impossible for a human body to radiate 460 w as you calculated in the previous part. which of the following alternatives seems to best explain this conundrum?
