How does the pressure at a certain depth in water differ from that of the same depth in river water. Explain year answer.

In what way does the temperature of water at the bottom of a waterfall differ from the temperature at the top ? Explain the reason.

How does the liquid pressure on a diver change if : (i) the diver moves to the greater depth, and (ii) the diver moves horizontally ?

How does a delta form at the meeting place of sea and river water?

An ocean depth finder shows the number of feet in the depth of water at a certain place. The difference between d, the actual depth of the water, and the depth finder reading , x, is |d-x| and must be less than or equal to 0.05d. If the depth finder reading is 620 feet, what is the maximum value of the actual depth of the water, to the nearest foot?

A bubble of 8 mole of helium is submerged at a certain depth in water. The temperature of water increases by 30^(@)C . How much heat is added approximately to helium during expansion

The pressure P_(1) at the top of a dam and P_(2) at a depth h from the top inside water (density rho ) are related as :

A man first swims in sea water and then in river water. (i) compare the weights of sea water and river water displaced by him. (ii) Where does he find it easier to swim and why?

A loaded cargo ship sails from sea water to river water? State and explain your observation.

A water barrel stands on a table of height h . If a small holes is punched in the side of the barrel at its base, it is found that the resultant stream of water strikes the ground at a horizontal distance R from the table. What is the depth of water in the barrel?

The spouting can is something used to demonstrate the variation fo pressure with depth. When the corks are removed from the tubes in the side of the can, water flows out with a speed that depends on the depth. In a certain can, three tubes T_(1),T_(2) and T_(3) are set at equal distance 'a' above the base of the can. When water contained in this can is allowed to came out of hte tubes, the distance on the horizontal surface are measured as x_(1),x_(2) and x_(3) . The correct sketch is
