A hall has 12 gates. In how many ways can a man enter the hall through one gate and come out through a different gate?

A horizontal oriented tube AB of length 5m rotates with a constant angular velocity 0.5 rad/s about a stationary vertical axis OO' passing through the end A. the tube is filled with ideal fluid. The end of the tube is open, the closed end B has a very small orifice. The velocity with which the liquid comes out from the hole (in m/s) is

Coffee is coming out from a conical filter, with height and diameter both are 15 cm into a cylindrical coffee pot with a diameter 15 cm. The rate at which coffee comes out from the filter into the pot is 100 cu cm/min. The rate (in cm/min) at which the level in the pot is rising at the instance when the coffe in the pot is 10 cm, is
