Part B You have probably seen people jogging in extremely hot weather. There are good reasons not to do this! When jogging strenuously, an average runner of mass 68 kg and surface area 1.75 m2 produces energy at a rate of up to 1300 W, 80% of which is converted to heat. The jogger radiates heat but actually absorbs more from the hot air than he radiates away. At such high levels of activity, the skin's temperature can be elevated to around 35.0°C instead of the usual 30°C. (Ignore conduction, which would bring even more heat into his body.) The only way for the body to get rid of this extra heat is by evaporating water (sweating). How much net heat per second does the runner gain just from radiation if the air temperature is 40.0°C? (Remember: He radiates out, but the environment radiates back in.) Express your answer with the appropriate units. Enter positive value if the person gives off heat and negative value if the person gains heat. HÅ ?

Part D How much water must the jogger's body evaporate every minute due to his activity? The heat of vaporization of water at body temperature is 2.42 x 106 J/kg Express your answer with the appropriate units. μΑ ? m = Value Units O The compound unit you entered is not recognized.
