If a copper wire is stretched to make radius 0. 1% thinner, then what is the percentage increase in resistance. Two wires of copper having the length in the ratio 4 : A string of length l is stretched by l/20 and speed of transverse wave along it is v. The ratio of longitudinal strain … 1 and their radii ratio as 1 : A 4m long copper wire of cross-sectional area 1. 2cm2 is stretched by a force of 4. 8×103n. The speed of wave when it is stretched by l/10 … 4 are stretched by the same force. A spring is stretched by applying a load to its free end. Youngs modules for copper y =1. 2×1011n … The strain produced in the spring is
