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.
