Fifty thousand ton ships are hollow inside. Fishing weights are not.
a big heavy steel ship floats on water because the volume is mostly air. trust me its true.
because of the ship's hull. it's volume is great as well as the density in addition it has air compartments.
The mass of water expelled by the ship is more than the mass of the ship. Hence the buoyant force is more than the weight of the ship and so ship floats.
You can infer very little about the density of the substance. Ships made of steel, with a density much greater than that of water, can float.
it floats
Whether a ship uses a river does not affect the depth- the depth affects whether or not a ship can use the river. Depth is affected by water flow, and the terrain the river runs through.
if the water the object displaces wieghs more than the object it self then it floats
Yes sonar can be used at periscope depth. Surface ships also have sonar arrays on them. They are usually used to detect submarines.
Locks help ships move from one level to another
Boats, ships and vessels do not collapse, they capsize. If they sink to depth with a enough air retained inside they may implode, but this more common in movies than in real life. When a vessel capsizes, one of three things happens. It simply rolls over and the hulls sticks out of the water. The vessel partially submerges and the remaining air partially floats the vessel or it sinks to the bottom, depending on the depth of water.

The weight of water displaced by the floating ship is less than the weight of the ship. So it floats. Thanks to Archimedes!
Same reason as any ships floats - the weight of the water that the hull can push aside is greater than the weight of the ship.
Some examples are, hot air ballons, ships, bouys, actually just about anything that floats in air or water :p
They caused anxiety and sink ships.
The location and information of the ships whereabouts are still classified by the United States Navy.
