Can you plz help me with the two questions plz?

so for the description of the ball come pout of water is:

Upward Buoyant Force forces the beach ball to go to the top of the pool.

and the force is: upward buoyant force

Explanation:

Buoyancy

Explanation:

The beach ball floats because this buoyant force, caused by water pressure, is stronger than the force of gravity pulling down on the ball.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
