Academics

Q1. An emf is induced in a conducting loop of wire 1.22 m long as its shape is changed from square to circular. Discover the average magnitude of the induced emf if the change in shape occurs in 4.25 s and the local 0.125 T magnetic field is perpendicular to the plane of the loop.

Q2. The power needed to operate your body is about 100 {rm watts}. Suppose your body could run on fusion power and could convert a total of 0.7 of its mass into energy. How much energy would be available through fusion? Assume the mass is 70kg.
