Question
Rubbing your hands together warms them by converting work into thermal energy.
a. If a woman rubs her hands a total of 19 times (forward and backwards count separately), at a distance of 7.75 cm per rub, and with an average frictional force of 39 N, what is the temperature increase of her hands, in degrees Celsius? The mass of tissues warmed is only 0.100 kg, mostly in the palms and fingers, and the heat capacity of her hands is 3500 J/(kg⋅°C).
