An elastic cord vibrates with a frequency of 3.4 Hz when a mass of 0.64 kg is hung from it. What is its frequency if only 0.34 kg hangs from it? Express your answer using two significant figures.

Step 1

The frequency of the elastic cord is,

Since the frequency of two hanging mass of the cord is,

Step 2

Divide the above two relation, to find the frequency of the second hanging mass of the cord.

Step 3

Substitute the ...
