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× 10^8 Pa. A steel ball of initial volume 0.32 m^3 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?

A 100 kg mass, fastened to the end of a steel wire of unstretched length 1 m, is whirled in a vertical circle with an angular velocity of 5 m/s at the bottom of the circle. The cross-sectional area of the wire is 0.070 cm^2 . Calculate the elongaton of teh wire when the mass is at the lowest point of its path ( Ysteel = 200 GPa ).
