Q1. A steel paper clip is bent by a force of 10.2 N exerted on it through a distance of 4.85 cm. By how much does temperature of the midsection of the paper clip increase if all the energy goes into the internal energy of this section that has a mass of 0.102 g?

Q2. A small rock with mass 0.14 is released from rest at point, which is at the top edge of a large, hemispherical bowl with radius = 0.52. Imagine that the size of the rock is small compared to, so that the rock can be treated as a particle, and imagine that the rock slides rather than rolls. The work completed by friction on the rock when it moves from point to point at the bottom of the bowl has magnitude 0.22. Just as the rock reaches point, what is the normal force on it because of the bottom of the bowl?
