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 2.0 m and circumference C= 0.8 m. For the Stefan-Boltzmann constant use o=5.67 x 10-8 W/m2/K. ▼ Part C Now calculate Por, the thermal power absorbed by the person from the thermal radiation field in the room, which is assumed to be at Troom = 20°C. If you do not understand the role played by the emissivities of room and person, be sure to open the hint on that topic. Express the thermal power numerically, giving your answer to the nearest 10 W.
