Embibe Experts Solutions for Exercise 3: Assignment

In the given figure, if the dimensions of the two wires are same but materials are different, then Young's modulus is

The length of wire, when $M_1$ is hung from it, is $I_1$ and is $I_2$ with both $M_1$ and $M_2$ hanging. The natural length of wire is

The substances having very short plastic region are

Due to addition of impurities, the modulus of elasticity

A load of $2 \mathrm{kg}$ produces an extension of $1 \mathrm{mm}$ in a wire of $3 \mathrm{m}$ in length and $1 \mathrm{mm}$ in diameter. The Young's modulus of wire will be

Young's modulus depends upon

A spherical ball contracts in volume by $0.01\%$ when subjected to a normal uniform pressure of $100 \mathrm{atm}$. The Bulk modulus of its material is

If the Bulk modulus of lead is $8.0\times {10}^9 \mathrm{N} {\mathrm{m}}^{-2}$ and the initial density of the lead is $11.4 \mathrm{g} {\mathrm{cc}}^{-1}$, then under the pressure of $2.0\times {10}^8 \mathrm{N} {\mathrm{m}}^{-2}$, the density of the lead is
