Question

A 5 . 5 m long string has a mass of 0 . 035 kg . If the tension in the string is 77 N , the speed of a wave on the string is, 110 m s - 1, 165 m s - 1, 77 m s - 1, 102 m s - 1

MARKS App · Accepted Answer

μ = 0.035 5.5 kg m - 1 , T = 77 N Velocity of transverse wave along string v = T μ = 77 × 5.5 0.035 = 110 m s - 1
