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 resonance air column of length 20 cm resonates with a tuning fork of frequency 250 Hz . The speed of sound in air is

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
