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.
If you dropped a cork in a container of water, the cork will most definitely float. As to the cork is lite, like a feather and it doesnt container much mass.
It depends on the shape of the fork and the material from which it is made. Most non-metal (wood, plastic) forks will float. Metal forks will sink unless they are shaped to have a large enough surface area on the bottom.
can float
unboiled eggs float, but the boiled ones sink.
Cork floats on mercury due to its low density compared to mercury. Mercury has a very high density, so most materials, including metals, will sink in it. Cork, being less dense, will float on the surface of mercury.
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.
Yes, a cork will sink in oil because cork is less dense than oil. The buoyant force acting on the cork will be greater than its weight, causing it to float.
No, mercury is denser than ethanol, so it will sink and not float.
If it is heaver than water (or what ever liquid you put it in) it will sink. Lead will sink. A cork will float.
Mercury is a heavy metal, it will sink in sea water.
Wooden cork is less dense than the water and the iron is not.
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.
Solid iron will float in liquid mercury. In most liquids it will sink.
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.
If the ice cube melts, the cork will float on the liquid water that was previously frozen as ice. Cork is less dense than water, so it will float rather than sink.
Lead will sink in liquid mercury because lead is denser than mercury. Mercury is a heavy liquid metal, so most metals will sink when placed in it.
