Two wires X and Y, made of same material are subjected to the same tension. Wire X has a length L and a cross sectional area A. Wire Y is of length A 2L and has a cross sectional area .A wave pulse 2 is sent from one end of each wire simultaneously. The pulse reaches the other end of the wire X in after a time T, while it takes a time T to reach the end of Y. We then have 2 a. T = 2 2 d. T = 2T e. T = 2T T b. T 7/2 c. T = T Activate
