Public television station kqed in san francisco broadcasts a sinusoidal radio signal at a power of 316 kw. assume that the wave spreads out uniformly into a hemisphere above the ground. a) at a home 5.50km away from the antenna, what average pressure does this wave exert on a totally reflecting surface? answer in pa unitsb)at a home 5.50km away from the antenna, what are the amplitudes of the electric and magnetic fields of the wave? answer in n/c, tc) at a home 5.50km away from the antenna, what is the average density of the energy this wave carries? answer in j/m^3d) for the energy density in part (c), what percentage is due to the electric field? e)for the energy density in part (c), what percentage is due to the magnetic field?
