A piece of metal floats on mercury. The coefficient of volume expansion of metal and mercury are `gamma_1 and gamma_2`, respectively. if the temperature of both mercury and metal are increased by an amount `Delta T`, by what factor does the fraction of the volume of the metal submerged in mercury changes ?

A

`(1)/( ( gamma_(2) - gamma_(1) ) Delta t) `

B

`( 1)/( ( gamma_(2) - gamma_(1) ) Delta t) `

C
