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. Submit Previous Answers Part B Correct Correct answer is shown. Your answer 2.09-10-11 = 2.09×10-11 Pa was either rounded differently or used a different number of significant figures than required for this part. At a home 4.00 km away from the antenna, what are the amplitudes of the electric and magnetic fields of the wave? Emar Bmax 1.54,5.13× 10-9 N/C,T Submit Previous Answers Part C Correct Important: If you use this answer in later parts, use the full unrounded value in your calculations. At a home 4.00 km away from the antenna, what is the average density of the energy this wave carries? Ο ΑΣΦ Submit Request Answer Part D '? J/m³ For the energy density in part (c), what percentage is due to the electric field? Ο ΑΣΦ Submit Request Answer Part E '? % For the energy density in part (c), what percentage is due to the magnetic field? Ο ΑΣΦ %
