Q1. An emf is induced in the conducting loop of wire 1.12 {rm m} long as its shape is changed from square to circular.
Find an average magnitude of the induced emf if the change in shape occurs in 4.24 {rm s} and the local 0.120-{rm T} magnetic field is vertical to the plane of the loop.
Q2. A bungee jumper, who's mass is 79 kg, jumps from a tall building. After reaching his lowest point, he continues to oscillate up and down, reaching the low point two more times in 8.2 s. ignore air resistance and assume that the bungee cord is an ideal spring, determine its spring constant.
