B4 A police officer's radar gun emits radio waves at a frequency of 11.3 GHz. What is the difference in the frequencies reflectedback to the radar gun by a car traveling at the 45 mph speed limit and a car travelling 1 mph faster? Assume that the cars are bothheaded directly away from the stationary officer.difference between frequencies:Hz A 2.81 µg particle moves at 2.01 x 10 m/s. What is its momentum p?kg-m/sTOOLSx10
