a.) Beale Air Force Base in Marysville hosts one of the nation's critical early warning radar systems. Named PAVE PAWS, it is designed to detect and track submarine- launched ballistic missiles originating from the Pacific Ocean. It operates at frequency 420 MHz and has an average power of 146 kW. Determine the magnitudes of the electric and magnetic field amplitudes at a distance of 10 km from the radar face. (Assume the radiation forms a uniform hemispherical shape.)
