(a) A shirtless rider under a circus tent feels the heat radiating from the sunlit portion of the tent. Calculate the temperature of the tent canvas based on the following information: The shirtless rider's skin temperature is 34.0oC and has an emissivity of 0.970. The exposed area of skin is 0.400 m2. He receives radiation at the rate of 20.0 W-half what you would calculate if the entire region behind him was hot. The rest of the surroundings are at 34.0oC.
(b) Discuss how this situation would change if the sunlit side of the tent was nearly pure white and if the rider was covered by a white tunic.
