Arectangular coil with sides 0.190 m by 0.220 m has 501 turns of wire. it is rotated about its long axis in a uniform magnetic field of 0.550 t that is perpendicular to the long axis. at what frequency, in complete cycles per second, must the coil be rotated for it to generate a maximum voltage of 115 v?

Aperson stands on a platform, initially at rest, that can rotate freely without friction. the moment of inertia of the person plus the platform is ip. the person holds a spinning bicycle wheel with its axis horizontal. the wheel has moment of inertia iw and angular velocity ωw. take the ωw direction counterclockwise when viewed from above. part a what will be the angular velocity ωp of the platform if the person moves the axis of the wheel so that it points vertically upward?
