Calculate the de-Broglie wave length of a Xe atom moving with velocity 2.4xx10^2ms^-1 the mass of Xe atom is 2.2xx10^(-25) kg .

A steel has a radius of 10mm and a length of 1.0m. A 100kN force stretches it along its length. Calculate stress and strain on the rod. Young's modulus of steel is 2.0 xx 10^11 Nm^-2 .

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?
