Question

The force stretching the D string on a certain guitar is 130 N. The string's linear mass density is 0.006 kg/m. What is the speed of the waves on the string?

Answer 1

Answer:

The value is  $v = 147.2 \ m/s$

Explanation:

From the question we are told that

    The force is   $F = 130 \ N$

     The linear mass density is  $\mu = 0.006 \ kg/m$

     

Generally the speed of the wave on the string is mathematically represented as  

            $v = \sqrt{\frac{F}{\mu } }$

=>        $v = \sqrt{\frac{130}{0.006} }$

=>        $v = 147.2 \ m/s$
