A convertible moves toward you and then passes you; all the while, its loudspeakers are producing a sound. The speed of the car is aconstant 8.93 m/s, and the speed of sound is 342 m/s. What is the ratio of the frequency you hear while the car is approaching to thefrequency you hear while the car is moving away?NumberUnits>#3CEm/s785%JU6וום&etyuApr 30560

You are standing on a train station platform as a train goes by close to you. As the train approaches, you hear the whistle sound at a frequency of f1 = 93 Hz.
