A guitar string is set into vibration with a frequency of 512 Hz.How many oscillations does it undergo each minute?
A)30,700
B)8.53
C)26.8
D)1610
E)512

To find the number of oscillations per minute, we need to convert the frequency from Hz to oscillations per minute. There are 60 seconds in one minute, so in one second, the guitar string oscillates 512 times.

Frequency = number of oscillations per second

Frequency = 512 Hz

Number of oscillations in one minute = 512 Hz x 60 seconds = 30,720 oscillations per minute

However, we need to be careful when rounding our answer. The closest option is A) 30,700.
