A steel wire has a length of 12.0 m and a mass of 2.10 kg . What should be the tension in the wire so that speed of a transverse wave on the wire equals the speed of sound in dry air at 20^(@)C = 343 ms^(-1)
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
A wire stretched betweentwo right supports vibrates in its fundamental mode with a frequency of 45 Hz. The mass of the wire is 3.5 xx10^(-2) kg and its linear mass density is 4.0 xx10^(-2) kg m^(-1) . What is (a) the speed of transverse wave on thestring . and (b) the tension in the string ?
A copper wire is held at the two ends by rigid supports. At 30^(@)C the wire is just tant, with negligible tension. Find the speed of transverse waves in this wire at 10^(@)C if Y=1.3xx10^(1!)N//m^(2), alpha=1.7xx10^(-5)l^(0)C and rho=9xx10^(3)kg//m^(3) .
