A spherical .ball.contracts in volume by 0.01% when subjected to a normal uniform pressure of two atmospheres. What is the bulk modulus of its material in C.G.S units?

The Marina trench is located in the Pacific Ocean, and at one place it is nearly eleven km beneath the surface of water. The water pressure at the bottom of the trench is about 1.1 xx 10^8 Pa. A steel ball of initial volume 0.32 m3 is dropped into the ocean and falls to the bottom of the trench. What is the change in the volume of the ball when it reaches to the bottom?

When the pressure on a sphere is increased by 80 atmospheres, then its volumes decreases by 0.01%. Find the bulk modulus of elasticity of the material of sphere.

Determine the volume contraction of a solid copper cube, 10 cm on an edge, when subjected to a hydraulic pressure of 7.0 xx10^6 Pa.

2.9g of a gas at 95^@C occupied the same volume as 0.184g of dihydrogen at 17^@C at the same pressure. What is the molar mass of the gas.

A brass wire 1.8 m long at 27^@C is held taut with little tension between two rigid supports. If the wire is cooled to a temperature of 39 ^@C , what is the tension developed in the wire, if its. diameter is 2.0 mm? Co-efficient of linear expansion of brass = 2.0 XX 10^-5 K^-1 Young’s modulus of brass = 0.91xx10^11 P

A bob of mass 0.1 kg hung from the ceiling of a room by a string 2 m long is set into oscillation. The speed of the bob at its mean position is 1 m s^1. What is the trajectory of the bob if the string is cut when the bob is (a) at one of its extreme positions, (b) at its mean position.

A metre stick is balanced on a knife edge at its centre. When two coins, each of masb 5 g are put one on top of the other at the 12.0 cm mark, the stick is found to be balanced at 45.0 cm. What is the mass of the metre stick?
