Suppose that a circular parallel-plate capacitor has radius R0 = 3.0 cm and plate separation d = 5.0 mm. A sinusoidal potential difference V = V0 sin(2πft) is applied across the plates, where V0 = 150 V and f = 60 Hz. In the region between the plates, find the magnitude of the induced magnetic field versus R and t, where R is the radial distance from the capacitor’s central axis. Assume that B = B0(R) is the amplitude of the magnetic field.

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.
