1. The state highway patrol radar guns use a frequency of 9.05 GHz. If you're approaching a speed trap driving 31.3 m/s, what frequency shift will your FuzzFoiler 2000 radar detector see?

2. The radar gun measures the frequency of the radar pulse echoing off your car. By what percentage is the measured frequency different from the original frequency? (Enter a positive number for a frequency increase, negative for a decrease. Just enter a number, without a percent sign.)
