Question

If youngs modulus of material of a rod is 2*10 11 and density is 8000kg time taken by a sound wave to trnsverse 1m of rod is

Answer 1

Young's Modulus = Y = stress/strain = σ / ε

Energy per unit volume =  U = 1/2 * stress * strain²

 U = 1/2 * σ * ε²

USE ABOVE FORMULAS AND PLZZ TRY CALCULATING IT.
