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

A stone hangs 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 frok. When the atone is immersed in water the length is changed to 32 cm to re-establish unison wtih the wire .Calculate the specific geavity of the stone

A stretched wire of length 1 m and weighing 1 gram is in unison with a tuning fork of frequency 200 Hz. The tension in the wire will be

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 stone hangs in air from one end of a wire, which is stretched over a sonometer. The wire is in unison with a certain tuning fork when the bridges of sonometer are 45 cm apart. Now the stone hangs immersed in water at 4^(@)C and the distance between the bridges has to be altered by 9cm to re-establish unison of the wire with the same fork. Calculate the density of the stone.

A sonometer wire is emitting a note a frequency n, when stretched by a weigth. If the weigth is completely immersed in water, then the frequency of the wire

A weight is attached to the free end of a sonometer wire. It gives resonance at length of 40 cm, when it is vibrating in unison with tuning fork of frequency 512 Hz. The weight is then immersed wholly in water, the resonating length is reduced to 30 cm. The relative density of the fluid in which weight is immersed is

A sonometer wire for which the length of the vibrating segment is 1.5 m is vibrating in its first overtone. It is in unison with a tuning fork of frequency 256Hz. Calculate the speed of the waves in the wire.
