A wire is in uniform with a tuning fork when stretched by a weight of density 9000 kg//m^(3) in a sonometer experiment . When the weight is immersed in water , the same wire produces 5 beats//s with the same fork. Find the frequency of the fork.

A sonometer wire resonates with a tuning fork. If the length of the wire between the bridges is made twice even then it can resonate with the same tuning fork. How ?

A sonometer wire is in unison with a tuning fork of frequency 150 Hz. If the tension in the wire is increased by 1%, how many beats per second will be heard ?

A sonometer wire is stretched by a solid mass M. It produces a fundamental note of a certain frequency in tune with a tuning fork when its length is 70 cm. When the mass is immersed in water it is found that the length has to be changed by 5 cm in order to bring it in tune with the same tuning fork. Calculate the relative density of the material of the hanging mass.

A 70 cm long sonometer wire is in unison with a tuning fork. If the length of the wire is decreased by 1.0 cm, it produces 4 beats per second with the same tuning fork. Find the frequency of the tuning

A stone in hung in air from a wire which is stretched over a sonometer . The bridges of the sonometer are 40 cm apart when the wire is in unison with a tuning fork of frequency 256 Hz . When the stone is completely immersed in water , the length between the bridges is 22 cm for re - establishing unison . The specific gravity of the material of the stone is

A sonometer wire is in tnison with a tuning fork of frequency 256 Hz, when the lenghts of the wire between the bridges is 75 cm and only one loop is formed. By keeping the lengths and tension constant, the wire is made to vibrate with 2 loops. The wire can still be in resonance with a tuning fork, provided the freqency of the tuning fork is
