An AM radio transmitter broadcasts 46.0 kW of power uniformly in all directions. Assuming all of the radio waves that strike the ground are completely absorbed, and that there is no absorption by the atmosphere or other objects, what is the intensity 33.0 km away? (Hint: Half the power will be spread over the area of a hemisphere.)

What is the maximum electric field strength at this distance?
