The diagram below shows the position of two divers A and B in river water at the depth of `h_1` and `h_2` respectively from the water surface.

The two divers were later made to dive in a sea. For the same depth, they experience more pressure in the sea compared to that in the river. Why?

The diagram below shows the position of two divers A and B in river water at the depth of h_1 and h_2 respectively from the water surface. Which of the two divers (A or B) will experience more pressure by the water?

An air bubble of radius r in water is at a depth h below the water surface at some instant. If P is atmospheric pressure, d and T are density and surface tension of water respectively . the pressure inside the bubble will be :

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 :

Assertion: At depth h below the water surface pressure is p . Then at depth 2h pressure will be 2p . (Ignore density variation). Reason: With depth pressure increases linearly.

A tank of height H is fully filled with water. If the water rushing from a hole made in the tank below the free surface , strikes the floor at a maximum horizontal distance , then the depth of the hole from the free surface must be

The area of two holes A and B are 2a and a , respectively, The holes are at height (H//3) and (2H//3) from the surface of water. Find the correct option(s):

In a cylindrical water tank there are two small holes Q and P on the wall at a depth of h_(1) from the upper level of water and at a height of h_(2) from the lower end of the tank, respectively, as shown in the figure. Water coming out from both the holes strike the ground at the same point. The ratio of h_(1) and h_(2) is

The diagram below shows two test-tubos A and B. Test-tube A contains a green water plant Test-tube B contains both a groen water plant and a snail. Both test tubes are kept n sunlight Answer the questions that follow Why does test-tube 'B' have more bubbles of oxygen

Two trees, A and B are on the same side of a river. From a point C in the river the distance of trees A and B are 25 m and 300 m respectively. If the angle C is 45^0 , find the distance between the trees (u s e\ sqrt(2)=1. 44)

Bharath went to his grandfather’s house in winter this year. As usual he went for fishing. His grandmother told him there will be no fishes in the lake. He noticed that it was more difficult to find fishes in winter. The fishes were deep inside the river. Whereas in summer they were on the surface and hence he was able to catch fishes. (a) Why are fishes on the surface in water than in the depth in summer? Srisha wanted to keep ice creams without melting. So he had to keep it on ice taken in a container. His grandmother advised him to pour salt on the ice. (a) Why? (b) What value can be derived from this?
