In one of the original Doppler experiments, a tuba was played at a frequency of 92.0Hz on a moving flat train car, and a second identical tuba played the same tone while at rest in the railway station.
Part A What beat frequency was heard in the station if the train car approached the station at a speed of 7.00m/s?
