A swimming pool appears .................. (deeper/shallower) than its actual depth.

The following figure shows the cross-section ABCD of a swimming pool which is a trapezium in shape. If the width DC, of the swimming pool is 6.4 m, depth (AD) at the shallow end is 80 cm and depth (BC) at the deepest end is 2.4 m, find its area of cross-section.

Assertion(A). A pool of water looks shallower than it actually is Reasoning (R). Light bends towarch the normal while travelling from water to air

STATEMENT -1 : An object is placed inside a liquid and screen through air perpendicularly look at shorter depth than its actual depth. and STATEMENT - 2 : When light passes from denser medium to rarer medium it deviates away from normal.

Water in a pond appears to be only three-quarter of its actual depth. (a) what property of light is responsible for this observation ? Illustrate your answer with the help of a ray diagram. (b) how is the refractive index of water calculated from its real and apparent depths ?

A fish is looking at a 1*0 m high plant at the edge of a pond. Will the plant appear to the fish shorter or taller than its actual height ? Draw a ray diagram to support your answer.

A rectangular swimming pool has a length of 30 meters, a width of 10 meters, and an average depth of 2 meters. If a hose can fill the pool at a rate of 0.5 cubic meters per minute, how many hours will it take the hose to fill the pool?

A balloon contains 14.0 L of air at 760 torr. What will be the volume of the balloon when it is taken to a depth of 10 ft. in a swimming pool? Assume that the temperature of the air and water are equal. (density : Hg=13.6g/mL.)

A swimming pool is 18m long and 8m wide. Its deep and shallow ends are 2m and 1.2m respectively. Find the capacity of the pool, assuming that the bottom of the pool slopes uniformly.

The perimeter of a rectangular swimming pool is 154 m. Its length is 2 m more than twice its breadth. What are the length and the breadth of the pool?

Two pipes of different diameters may be used to fill a swimming pool. The price with the larger diameter working alone can fill the swimming pool 1.25 times faster than the other pipe when it works alone. One hour after the larger pipe is opened, the smaller pipe is opened, and the swimming pool is filled 5 hours later. Which equation could be used to find the number of hours, x, it would take for the larger pipe to fill the pool working alone?
