Question

A piano tuner strikes her tuning fork and plays a note on the piano at the same time. She hears 8 beats in 4 seconds. How much should the pitch of the string be changed?

A. 8 Hz

B. 4 Hz

C. 2 Hz

D. 0.5 Hz

Answer 1

The answer would be d Bc 4 is half of 5 and 0.5 is a half

Answer 2

C

Step-by-step explanation:

The number of beats per second produced when two sounds are played together is equal to the difference in frequencies between the two sounds. Since 8 beats are produced in 4 seconds, 2 beats will be produced in one second, and the frequency difference is 2 Hz.
