A coil lies on the x-y plane and is in a region in which a 3.0 T uniform magnetic field makes an angle of 55 degrees with the plane of the loop. If the flux is 5.0 Wb, find the area of the coil.

Aplayground merry-go-round has a radius of 4.6 m and a moment of inertia of 200 kg-m2 and turns with negligible friction about a vertical axle through its center. a child applies a 26.0 n force tangentially to the edge of the merry-go-round for 15.0 seconds. if the merry-go-round is initially at rest, how much work did the child do on the merry-go-round?
