4 are stretched by the same force. A string of mass 2. 50 kg is under a tension of 200 n. A slightly conical were of length l and end radii and is stretched by two forces and applied parallel to length in opposite direction and normal to end faces, if y denotes the youngs modulus. When we think of potential energy, often the first thing that we can imagine is an object high in the air and just starting … A 4m long copper wire of cross-sectional area 1. 2cm2 is stretched by a force of 4. 8×103n. Two wires of copper having the length in the ratio 4 : If a copper wire is stretched to make radius 0. 1% thinner, then what is the percentage increase in resistance. The speed of wave when it is stretched by l/10 will be (assume that hookes law is applicable) A string of length l is stretched by l/20 and speed of transverse wave along it is v. 1 and their radii ratio as 1 : The strain produced in the spring is We have studied earlier that due to disturbance in stretched string transverse waves are generated. Potential energy is the energy that an object has stored in it due to its position. If a copper wire is stretched to make its radius decrease by 0. 1 %, the percentage changes in its resistance is approximately −0. 4 % +0. 8 % +0. 4 % +0. 2 % Youngs modules for copper y =1. 2×1011n /m2 the increase in length of wire is The length of the stretched string is 20. 0 m. Hence, to calculate the velocity of transverse waves, let us assume a string, whose unit length mass … If the transverse jerk is struck at one end of the string, how long does he disturbance take to reach the … A spring is stretched by applying a load to its free end. The ratio of longitudinal strain in the two will be:
