An emf is induced in a conducting loop of wire 1.12m long as its shape is changed from square to circular. Find the average magnitude of the induced emf if the change in shape occurs in 4.25 seconds and the local 0.105 T magnetic field is perpendicular to the plane of the loop.

Two students, each riding bicycles, start from the same apartment building and ride to the same building on campus, but each takes a different route. the first student rides 1100 m due east and then turns due north and travels another 1430 m before arriving at the destination. the second student heads due north for 1930 m and then turns and heads directly toward the destination.at the turning point, how far is the second student from the destination?
