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.

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.

A sonometer wire emits a note of frequency 150 Hz.What will be the frequency of the note emitted by it if its tension increaeed in the ratio 9:16 and the length is doubled?

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.

Establish by dimensional analysis that v= sqrt(T/m) where v is the velocuty of wave along the stretched wire.T is tension applied and m is mass per unit length of the wire.

A current of 10A flows through each of two parellel long wires. The wies are 5cm apart. Calculate the force acting per unit length of each wire.

A metallic wire 1 m in length is moving normally across a field of 0.1T with a speed of 5ms^(-1) . Find the emf between the ends of the wire.

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 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 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?
