Answer 1

Zero!

Thanksssss!!!!!!!!!!!

Answer 2

A rod of length L is fixed between two rigid supports and supplied heat to raise its temperature T. If y is the coefficient of volume expansion of the wire and y is young's modulus of the wire then the elastic potential energy density stored in the wire is A) V*I*y 2.
