A wire of length L_0 is supplied heat to raise its temperature by T. g

1.	A wire of length L_0 is supplied heat to raise its temperature by T. gamma is the coefficient of volume expansion of the wire and Y is Young's modulus of the wire then the energy density stored in the wire is
Answer» `(1)/(2) gamma^(2) T^(2) Y` `(1)/(3) gamma^(2) T^(2) Y^(3)` `(1)/( 18) ( gamma^(2) T^(2) )/( Y)` `( 1)/( 18) gamma^(2) T^(2) Y` ANSWER :D
