Ozone is spread in the swimming pool because:

Ozone is pumped in to the swimming pool because

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?

A swimming pool appears to be 6 m deep. Refractive index of water with respect to air, n_w = 4//3 . The real depth of the swimming pool is

A swimming pool 70 m long, 44 m wide and 3 m deep is filled by water flowing from a pipe at the rate of 30,800 cm^(3) per second. The time taken to fill the swimming pool is:

A stone S is on the bottom of a swimming pool. The depth of the lying pool is d and index of refraction of water is mu . What is the depth of the swimming pool visible to a normal eye ? Cheak the results with d=6ft and mu=1.5 .

find the in which parts is error Children are not allowed to use the swimming pool unless they are with an adult.

Boric acid is added to talcum powder (for babies) and chlorine is added to water in swimming pools. Why?

Give scientific reasons: It is easy to swim in a swimming pool than in a river.
