Apolice car on the side of the road (at rest) uses a radar gun to catch speeders as they approach it. the frequency the radar gun emits is 8 x 10^9 hz and the speed limit is 65 mi/hr. what is the difference in frequency of the emitted and returned radar wave? (a positive answer means the returned wave has a greater frequency than the emitted wave; a negative answer means the returned wave has a smaller frequency than the emitted wave.)
