"A guitar string is set into vibration with a frequency of 512 Hz. How many oscillations does it undergo each minute?"

30720 oscillation.

Explanation:

Frequency: This can be defined as the number of oscillation completed in a seconds. The S.I unit of frequency is Hertz.

From the question,

The frequency of the string set is 512 Hz,

These means that the spring set complete 512 oscillation in one seconds

I.e

if its completes in one seconds 512 oscillation.

Then, in one minutes, it will complete x oscillation.

x = 512×1min/1seconds

But 1 minutes = 60 seconds

x = 512×60/1

x = 30720 oscillation.

this is poiselle's equation from fluid mechanic in physics. mech eng
