QUESTION:
Problem 30P
It was shown in Example that atypical person radiates about 62 W of power at room temperature. Given this result, how long does it take for a person to radiate away the energy acquired by consuming a 230-Calorie doughnut?
ANSWER:
Step 1 of 2
We can calculate the time required by dividing the energy content of a donut by the radiation rate of a person. We use conversion factors to express the value in the desired unit. So, from the mechanical equivalent of heat,
