(a) area of the hole
(b) density of the liquid
EXPLANATION:
The velocity of the liquid coming out of a hole in a tank is given as V =√(2gh) where h is the height of the liquid from the hole and g is the acceleration due to gravity. Clearly, V depends on g and h only. It does not depend on the area of the hole and the density of the liquid.
Hence the options (a) and (b) are true but the options (c) and (d) are not true.
