In a game of football outdoors on a cold day, a player will begin to feel exhausted after using approximately 8.0 x 10 J of internalenergy. (a) One player, dressed too lightly for the weather, has to leave the game after losing 7.0 x 10° Jof heat. How much work has hedone? (b) Another player, wearing clothes that offer better protection against heat loss, is able to remain in the game long enough to do2.3x 105 J of work. What is the magnitude of the heat that he has lost?(a) NumberUnits(b) NumberUnits<.

Given : ∆U = -8 × 105 J (negative because internal energy is lost before being exhausted) In part…

A 68 kg cyclist is pedaling down the road at 15 km/h, using a total metabolic power of 480 W. A certain fraction of this energy is used to move the bicycle forward, but the balance ends up as thermal energy in his body, which he must get rid of to keep cool. On a very warm day, conduction, convection, and radiation transfer little energy, and so he does this by perspiring, with the evaporation of water taking away the excess thermal energy. To keep from overheating, the cyclist must get rid of the excess thermal energy generated in his body. If he cycles at this rate for 2 hours, how many liters of water must he perspire, to the nearest 0.1 liter?A. 0.4 L B. 0.9 L C. 1.1 L D. 1.4 L
