When a current of 0.05 mA passes through a bulb , what is the charge passing through it in five minutes ?

In what direction does the medium move relative to the direction of the wave? explain.

Which configuration would produce an electric current? a) rotate a coil of copper wire between two magnets. b) connect a wire between a copper and zinc strip sitting in a beaker of water. c) connect a wire to the (+) positive end of a battery and the other end to a light bulb. d) connect a wire to the negative end of a battery and the other end to a light bulb.

How does changing the frequency affect the energy of the wave?
