A uniform pressure P is exerted by an external agent on all sides of a solid cube at a temperature t $$^{0}C$$.By what amount should the temperature of the cube be raised in order to bring its volume back to its original volume before the pressure was applied if the bulk modulus is B and coefficient of volumetric expansion is $$\gamma $$

In Youngs expt., the distance between two slits is d/3 and the distance between the screen and the slits is 3D. The number of fringes in 1/3 m on the screen, formed by monochromatic light of wavelength $$3\lambda $$, will be? 

The Poissons ratio for inert gases is:

If $$S $$ is stress and $$Y$$ is the Young's modulus of the material of a wire, the energy stored in the wire per unit volume is :

The load versus strain graph for four wires of the same material is shown in the figure. The thickest wire is represented by the line

Four uniform wires of the same material are stretched by the same force. The dimensions of wire are as given below. The one which has the minimum elongation has :

A rubber ball is brought into 200 m deep water, its volume is decreased by 0.1% then volume  elasticity coefficient of the material of ball will be:
$$(Given\ \rho = 10^3 kg/m^3$$ and $$ g = 9.8 ms^{-2})$$

(i) For a Searle's experiment, in the graph shown, there are two readings a and b that are not lying on the straight line
(ii) Experiment is not performed precisely

The velocity of sound in glass in 50. 0m/sec, it's density is 2,927 gm c.c. Calculate Youngs modules of glass in dynes/cm$$^{2}$$

A sample of a liquid has an initial volume of $$1.5 L$$. The volume is reduced by $$0.2 mL,$$ when the pressure increases by $$140 kPa$$. What is the bulk modulus of the liquid.
