What is surface tension and what phase of matter creates it?

The property of the surface of a liquid that allows it to resist an external force, due to the cohesive nature of its molecules.The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension.

If i'm wrong correct me.

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
