State hooke’s law?
Hooke’s law states that the extension produced in the wire is directly proportional to the load applied within the elastic limit i.e. Acc to Hooke’s low Stress α Strain Stress = E x Strain E = Modulus of elasticity

Define modulas of elasticity and write down its Unit and Dimensions.
Modulus of elasticity = Stress / Strain, As Strain is a dimensionless quantity being a ratio between change in dimension to the original dimension, the dimensions of Modulus of Elasticity are the same as that of stress. That is kg/mm^2 are the dimensions of Modulus of Elasticity.
Write down the relation beween three types of moduli and poissons ration?
3 Types of Elastic Moduli. Young's modulus (E) describes tensile elasticity, or the tendency of an object to deform along an axis when opposing forces are applied along that axis; it is defined as the ratio of tensile stress to tensile strain. It is often referred to simply as the elastic modulus.
One kg of a diatomic gas is at a pressure of 8 × 104 N/m2 . The density of the gas is 4 kg/m-3. What is the energy of the gas due to its thermal motion?
3 × 104 J
5× 104 J
6× 104 J
7× 104 J
B.
5× 104 J
Thermal energy corresponds to internal energy
Mass = 1 kg
density = 8 kg/m3
