1.	A piece of metal floats on mercury. The coefficients of volume expansion of the metal and mercury are gamma_(1) " and " gamma_(2) respectively. If their temperature is increased by DeltaT, then by what factor does the fraction of the volume of metal submerged in mercury change?
Answer» ANSWER :`((1+gamma_(2)DELTAT)/(1+gamma_(1)DeltaT))`
