F4) You are an inspector for the Federal Communications Commission. A radio station is licensed to broadcast at a power of \( 15.0 \) kilowatts, but you suspect that they sometimes increase broadcast power above that. You set up a receiver \( 2.00 \) kilometers from their broadcast towers. You measure that the r.m.s. magnetic field produced by their signal, at that distance, is \( 1.33 \times 10^{-9} \) Tesla. At what power are they really broadcasting? (Assume spherical spreading of their radio waves.) (10 points)
