Chapter 14, Problem 5PE
Rubbing your hands together warms them by converting work into thermal energy. If a woman rubs her hands back and form for a total of 20 rubs, at a distance of 750 cm per rub, and with an average frictional force of 40.0 N, what is the temperature increase? The mass of tissues warmed is only 0.100 kg, mostly in the palms and fingers.
