about............50m......i think
The weight must be less than the buoyant force. Push down on a floating cork and it will sink below the surface. Stop pushing and remove your hand, and the cork's buoyancy will take over and the cork will float again.
no the cork will sink
It didn't.
it floats
Oil is denser than cork, so the cork would float.
no
If it is heaver than water (or what ever liquid you put it in) it will sink. Lead will sink. A cork will float.
Wooden cork is less dense than the water and the iron is not.
No Japan isn't sinking that is what i think
Yes, a cork will often float on the surface of water, depending on the cork's density. But a marble will sink in water because of its weight. It will not float on the surface.
just a sink Below surface (grade) sink
A cork is able to float on water because it is less dense than the water. The reason why is because an object with more dense then itself it will float and an object with less density will sink in the fluid. HOWEVER if the object (such as the cork) has the same density, the object will neither float nor sink; instead it will stay at the same level in the fluid. So TECHNICALLY it is considered floating. So corks count as floating because it has less dense than the water. Sources: (Science: Glenco textbook)
