If you take 42.0 meters of string and ball it up and put it on a scale you measure that it weighs 18.8 grams. if you tighten a length of this same string to a tension of 8.5 newtons, what is the wave speed for waves that would travel on this string when you plucked it?

137.74 m/s

Explanation:

= length of the string = 42 m

 = mass of the string = 18.8 g = 0.0188 kg

Linear mass density is given as

 = 0.000448 kg/m

 = wave speed

 = Tension force in the string = 8.5 N

Wave speed is given as

 = 137.74 m/s
