Question

A string 2.50 m long has a mass of 0.00350 kg. Calculate the speed of mechanical waves in this string when it is under a tension of 0.900 N.

Answer 1

It sounds as it is relatively straight froward (no pun intended).

V=sqrt(T/u)
V- velosity of the wave
T= tention on the string
u = lineas mas density

V=sqrt(T/(m/l))
That w=sj=hould do it
V=sqrt(.900/(0.00350 /2.50 )
V=25.4 m/s
