A flask has a base of radius 12 cm and narrows to a neck of radius 6 cm. It’s filled to the base of the neck with water. If 5.5x10-4 m3 of additional water is poured into the flask, by how much does the force of the water on the base increase?

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

float.

archimedes' principle

denser than water sinks in water.

denser than mercury would sink in it
