You have a string with a mass of 0.0123 kg.0.0123 kg. You stretch the string with a force of 8.37 N,8.37 N, giving it a length o

Answer:

v= 35.09m/s

f= 38.77Hz

Explanation:

Length 'L' = 1.81 m

Now, First off the fourth harmonic of a string with two nodes is given by:

L=2λ

1.81=2λ

λ= 1.81/2 =>0.905 m

Wave speed on a strecthed string is:

v=√(Ft/(m/l))

v= √(8.37)/(0.0123/1.81)

v= 35.09m/s

Next is to determine frequency i,e

v=λf or f =v/λ

f= 35.09/0.905

f= 38.77Hz
