Question

There is a small hole near the bottom of an open tank filled with a liquid. The speed of the water ejected does not depend on
(a) area of the hole
(b) density of the liquid
(c) height of the liquid from the hole
(d) acceleration due to gravity

Answer 1

Answer:

Explanation:

(d)acceleration due to gravity.

Answer 2

The correct answers are (a) and (b).

Explanation:

• The liquid flowing from the hole has the emergent speed v. It flows in the tank’s bottom and it is shown as v = 2gh.
• Here, h is liquid’s height from the hole and g is acceleration due to gravity.
• So, it is understood that the liquid’s speed depends on the liquid’s height from the hole and on the acceleration due to gravity. So, the speed of the water does not depend on the density of the liquid and the area of the hole.
