Velocity of a wave in a wire is v when tension in it is `2.06 × 10^4 N`. Find value of tension in wire when velocity of wave become `v/2`.

A transverse wave travels on a taut steel wire with a velocity of when tension in it is 2.06xx10^4 N . When the tension is changed to T, the velocity changed to 3v. The value of T is close to :

A transverse wave travels on a taut steel wire with a velocity of v when tension in it is , 2.06times10^(4)N .When the tension is changed to T ,the velocity changed to v/2 . The value of T is close to : ?

The length of a metal wire is 10cm when the tension in it is 20N and 12cm when the tension is 40N . Then natural length of the wire is in cm

The length of a metal wire is l_1 when the tensionin it is T_1 and is l_2 when the tension is T_2 . The natural length of the wire is

The length of a metal wire is l when the tension is F and x l when the tension si y F. Then the natural length of the wire is

The length of a wire l_(1) when tension is 4 N and l_(2) when the tension is 5 N. Then its original length would be

The length of a metal wire is l_(1) when the tension in it is T_(1) and is l_(2) when the tension is T_(2) . Then natural length of the wire is

A load of 20kg is suspended by a steel wire in a sonometer experiment. Velocity of waves when the wire is rubbed with a resined cloth along the length is 20 times the velocity of waves in the same string, when it is plucked. Find area of cross-section of the wire, if Y for steel is 19.6xx10^(10)N//m^(2) and g =9.8m//s^(2) .

The length of a metal wire is l_(1) when the tension in it is F_(1) and l_(2) when the tension becomes F_(2) . Find the natural length of wire.
