Two loudspeakerse are mounted on a merry go round whose radius is 9.01m. When stationary the speakers both play a tone whose frequency is 100 Hz. They are situated at opposite ends of a diameter. The speed of sound is 343 m/s and the merry go round revolves once every 20s. What is the beat frequency that is detected by the listener when the speakers are both pointing at him from equal distances?
