The marianas Trench, a region at the bottom of the Pacific Ocean is believed to be the deepest spot on the ocean floor. In 1960. a U.S Navy submersible vehicle werit to a spot in this Trench that is 10.700 m below sea level. Suppose the submarine had a tiny window of area 1cm^2 so that sailors could enjoy the view. Find the force on this window due to the water pressure. Comment on the result.

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 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? Bulk modulus for steel = 1.6 xx 10^(11) Nm^(-2) .

This item consists of two statements, Statement I and Statement II. Statement I: The Kuroshio is a warm north-flowing ocean current on the west side of the North Pacific Ocean. Statement II : Presence of a number of volcanoes at the bottom of the Sea of Japan is responsible for the Kuroshio becoming warm. Examine these two statements carefully and select the answer to the item using the code given below.

Depth of sea is maximum at Mariana Trench in West Pacific Ocean. Trench has a maximum depth of about 11km . At bottom of trench water column above it exerts 1000 atm pressure. Percentage change in density of sea water at such depth will be around (Given , B = 2xx10^(9) Nm^(-2) and P_(atm) = 1xx10^(5 Nm^(-2)))
