A flat circular coil with 135 turns, a radius of 2.28 x 10-2 m, and a resistance of 0.618 is
exposed to an external magnetic field that is directed perpendicular to the plane of the
coil. The magnitude of the external magnetic field is changing at a rate of AB/At = 0.615
T/s, thereby inducing a current in the coil. Find the magnitude of the magnetic field at the
center of the coil that is produced by the induced current.

- Required information A bungee jumper leaps from a bridge and undergoes a series of oscillations. Assume g = 9.78 m/s². If a 60.0-kg jumper uses a bungee cord that has an unstretched length of 30.1 m and she jumps from a height of 45.2 m above a river, coming to rest just a few centimeters above the water surface on the first downward descent, what is the period of the oscillations?
