A steel wire 0.72 m long has a mass of 5.0 xx 10^(-3) kg. If the wire is under a tension of 60 N. What is the speed of transverse waves on the wire ? |

Answer» Solution :Mass PER unit length of the wire, `mu = (5.0 x 10^(-3) kg)/(0.72 m)` `= 6.9 xx 10^(-3) kg m^(-1)` Tension, T = 60 N The SPEED of wave on the wire is GIVEN by `V = sqrt((T)/(mu)) = sqrt((60 N)/(6.9 xx 10^(-3) kg m^(-1))) = 93 s^(-1)` |
