Hydrogen chrolide gas is sent into a 100 metre tube from one end 'A and ammonia gas from the other end 'B', under similar conditions. At what distant from 'A' will be the two gases meet.

A 100 meter hollow tube of uniform thickness has two open ends X and Y. Ammonia gas is sent into the tube from end X and hydrogen chloride from end Y, simultaneously. At what distance from end 'X', the gases first meet to form a smoke ring?

The mass of an uniform ladder of length l increases uniformly from one end A to the other end B, find the position of the centre of mass from end A.

In a tube of length 5m having two identical holes at the opposite ends. H_(2) and O_(2) are made to effuse into tube from opposite ends under identical conditions. Find the point where gases will meet for the first time
