A sonometer wire is under tension of 40 N and the length between the two bridges is 60 cm.A one metre long wire of the sonometer has a mass of 1.0 g.Deduce the speed of transverse waves and the frequency of the second harmonic.

A wire is under tension of 32N and the length between the two bridges is 1 metre.A 10 metre length of the sample has a mass of 2g.Deduce the speed of transverse waves on the wire and the frequency of the fundamental.

A steel wire 0.72m long has amss of 5.0 xx 10^3 kg . If the wire is under the tension of 60N, what is the speed of transverse wavs on the wire?

A tuning fork has got a frequency equal to the fundamental frequency of 25 cm length of a sonometer wire.Without change the load,if the legth of the wire is increased to 25.5 cm then 3 beats are heard per secondwhen the fork and wire are made to vibrate together.Calculate frequency of the tuning fork.

The length between two bridges of a sonometer wire is L, tension is T and the fundamental frequency is N, if the length between the bridges and tension both are doubled, explain if there is any change in fundamental frequency.

A metal wire of linear mass density of 9.8 gm^-1 is stretched with a tension of 10kg wt between two rigid supports of 1 metre apart. If the wire is allowed to vibrate in its fundamental frequency, then find the frequency of vibration.

Two tuning forks when sounded together give 4 beats per second.if one of them is in unison with 96 cm length of a monochord under constant tension and the other with 97 cm length of the same string,find the frequencies of the fork.

A wire with mass per unit length 0.05 gcm^-1 is stretched between two rigid supports with tension of 4.5xx(10)^7 dynes.it is observed that the wire resonates at a frequency of 420 Hz.The next frequency at which the wire resonates is 492 Hz.Find the length of the wire.

Find the force between two straight parallel wires, each of length one metre and cach carrying a current of 100 amperes when separated by a distance of one metre (given mu_0 = 4pi x 10^-7 N/m) .

A string 25 cm long and having a mass of 2.5 g is under tension.When the string is vibrating in its first overtone and air in a 40 cm long closed pipe in its fundamental frequency 8 beats per second are heard.it is observed that decreasing the tension in the string decreases the beat frequency.Find the tension in the string.[Velocity of sound is 320 m/s]

A U-shaped wire is dipped in a soap solution, and removed. The thin soap film formed between the wire and the light slider supports a weight of 1.5 xx10^-2 N (which includes the small weight of the slider). The length of the slider is 30 cm. What is the surface tension of the film?
