A student warms a metal temperature sensor by rubbing it in between their hands. Calculate the rise in temperature if the sensor is held with a force of 100 N, moved a distance of 4 cm per rub and rubbed 20 times.

mass of sensor = 10 g
coefficient of dynamic friction of  hands = 0.9
coefficient of static friction of  hands = 1.0
Specific heat capacity sensor = 500 Jkg^-1K^-1
