1. Rubbing your hands together warms them by converting work into thermal energy. If a woman rubs her hands back and forth for a total of 16 rubs, at a distance of 7.5 cm per rub, and an average frictional force of 37 N: a) What is the amount of energy transfered to heat? Q= b) What is the temperature increase if the mass of the tissue warmed is 0.100 kg and the specific heat capacity of the tissue is 3.49 kJ/(kg °C)? AT= °C
