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?

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?

Two identical pieces, one of ice (density =900kgm^(-3)) and other of wood (density =300kgm^(-3) ) float on water. a. Which of the two will have more volume summerged inside water? b. Which of the two will experience more upthrust due to water?

The diagram below shows a point source P inside a water container. Four rays A, B, C, D starting from the source P are shown up to the water surface. Show in the diagram the path of these rays after striking the water surface. The critical angle for water air surface is 48^(@) .

The diagram below shows a point source P inside a water container. Four rays A, B, C, D starting from the source P are shown up to the water surface. Name the phenomenon which the rays B and D exhibit.

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

The height of the water in a tank is H. The range of the liquid emerging out from a hole in the wall of the tank at a depth (3H)/4 from the upper surface of water, will be

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 Give an example of a water plant that can be used in the above experiment.

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-tubes A and B. Test-tube A contains a green water plant Test-tube B contains both a green water plant and a snail. Both test tubes are kept in sunlight Answer the questions that follow What is the purpose of keeping a snail in test-tube "B?

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):
