Explanation:
From the question we are told that
The speed of the ride
The frequency of the oboe is
The temperature outside is
Generally the speed of sound generated in air is mathematically evaluated as
Substituting value
The frequency of sound(generated by the musician on he park) getting to the musicians on the unicycle is mathematically evaluated as
substituting values
Since the musician on the park is not moving the frequency of sound (from the musicians riding the unicycle )getting to him is = 440Hz
The beat frequency these musician here is mathematically evaluated as
So
