Because cork is less dense than water.
A cork would float in water because it is less dense than water. This means that the cork displaces an amount of water equal to its weight, causing it to float on the surface of the water.
No, a wooden cork would float in a tank of water because wood is less dense than water. The cork displaces an amount of water equal to its weight, which allows it to float.
A cork has a low density. It is lower then water. That causes it to float.

Cork is a light weight wood product that will float in water.
Oil is denser than cork, so the cork would float.
The cork will float on the surface of the water because cork is less dense than water. The cork displaces a volume of water equal to its own weight, allowing it to float. If the cork is pushed under water, it will pop back up due to its buoyant force.
Yes, a magnet can float on a cork in water because the cork provides buoyancy to keep the magnet afloat. The buoyant force of the water supports the weight of the cork and the magnet, allowing them to float together.
Cork is lighter than most types of wood and would therefore float higher (or better) in the water.
Depends on the medium, and whether the ball is solid or not. A solid ball would float on mercury, sink in water. If it were hollow enough (or filled with, say, cork) it would float in water.
Only if the beaker is very full and the surface is rounded. Otherwise, the cork will float to the edge of the container (which is typically the highest part of the water).
