It depends on the density of a substance, if it can float or not. If its mass per volume is less than the one of water, it floats. That means overall that the same volume of water would have a bigger weight than the one of the ship... and it floats... By the way: The volume of water the ship pushes away (under the water line) while floating, has just the weight of the ship. So if you're talking about a certain water deplacement of a ship, you're actually talking about the ship's weight ;-). Vic
It can do so, because a ship is lighter than the weight of the water it displaces. As it displaces water, the pressure upwards maintains its buoyancy. Ultimately, if a ship displaces the amount of water just about equal to the weight of the ship, it will remain buoyant. However, if the ship is heavier than the water it displaces, then it will sink. This is famously known as the Archimedes Principle.
It is because the weight of the vessel and oil is less than the weight of the volume of water it displaces.
Metal ships are built to float.
boyancy in the hull of the ship
An object will float on water if it has less density than the water.
its anything that can float in sea like a submarine,ship, yacht etc
A sea comprised of liquid, with the greatest possible density.
ship float in the sea because water has less density than any substance ship has much weight and thatswhy it sinks
"average density" You must combine the weight of the metal hull with that of the air contained within it.
It depends. A steel ship will float just fine, so will an iron one(i.e. Old Ironsides). It all depends on the size, weight, and buoyancy of the ship.
Mercury is a heavy metal, it will sink in sea water.
A needle is fully metal whereas a ship is hollow so it floats
It displaces water and is filled with air.
The water of the Dead Sea is unusually salty (even for a sea) and hence, it is also unusually dense.
