=8.7
I hope this helped :)
Answer:
2.97795 Hz
Explanation:
v = Speed of sound in air = 343 m/s
= Relative speed between the speakers and the student = 1.12 m/s
= Actual frequency of sound = 456 Hz
Frequency of sound heard as the student moves away from one speaker
Frequency of sound heard as the student moves closer to the other speaker
The difference in the frequencies is
The student hears 2.97795 Hz
