If one of the pipes has a much smaller diameter than the other and are placed horizontally then form both sides of Bernoulli's equation, we can drop the term
A ball of mass m moving with uniform speed collides elastically with another stationary ball. The incident ball will lose maximum kinetic energy when mass of the stationary ball is
The density of water is 103kg/m3. The water pressure on a submarine is 2.0 x 107N/m2. The depth of the submarine below the surface of the water, in maters, is approximately
