Public television station KQED in San Francisco broadcasts a sinusoidal radio signal at a power of 777 kW. Assume that the wave spreads out uniformly into a hemisphere above the ground. Part A At a home 5.50 km away from the antenna, what average pressure does this wave exert on a totally reflecting surface? Express your answer in pascals
Part B At a home 5.50 km away from the antenna, what are the amplitudes of the electric and magnetic fields of the wave? Express the electric field amplitude in newtons per coulomb. Express the magnetic field amplitude in teslas. Enter your answers numerically separated by a comma.
Part C At a home 5.50 km away from the antenna, what is the average density of the energy this wave carries? Express your answer in joules per meter cubed.
Part D For the energy density in part (c), what percentage is due to the electric field? Express your answer as a percentage
