Why do needle sinks in water but ship floats?
Whether something sinks when it's placed on water is determined by the amount (weight) of water that it displaces. The needle, being small in size and relatively high in mass (relative to its size), displaces very little water when it is placed on the surface. The weight of the needle will be more than the weight of the water that it displaces and the needle will sink. The ship, though many times heavier than the needle, will displace alot more water than the needle. The ship will float if the weight of the displaced water is more than the weight of the ship.
Why is ship floating on the water but it is made of metal?
Because the volume of water it displaces weighs more than the ship. Archimedes principle says that the upwards force on the ship is equal to the weight (mass) of fluid displaced - so the ship floats
Why as a ship in harbour is being unloaded it slowly rises in higher?
the ship floats because its weight per volume (density) is less than water. When unloaded its weight is less and Archimedes principle says a body is equal in weight to the weight of the water it displaces; less weight displaces less water so ship rises
Why does the buoyant force keep a ship floating?
The buoyant force on a ship (or any object in a liquid) is equal to the weight of the water the displaces. If this force is greater than the weight of the ship, it will stay afloat.
What is reason that a steel ship floats while a steel needle sinks?
The displaces a sufficient amount of water to keep it afloat
Why does metal ship float on sea?
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
How do you weight a ship?
Archimedes principle. See how much water it displaces.
How is the ship less dense than water?
The amount of water the ship displaces is equal to it's own weight according to the Archimedes' principle. The more water it displaces, there is the more "buoyant"/ float-able it becomes according to the law of floatation.
Explain why a ship that is mostly made of metal float on the water?
It displaces water and is filled with air.
How balloons and blimps are able to fly in oceans of air?
Balloons float because of the same principal as how ships float: bouyancy. A ship displaces a volume of water. If the ship's weight is less than the volume of water that it displaces, then it will float. Same is true for a balloon. It displaces a volume of air. If the Hydrogen or Helium in the balloon weighs less than the volume of air it displaces, then it will rise.

How the ship floats on sea?
Displacement - the ship displaces an amount of water equal to its weight. Provided that this dowes not submerge the vessel, it will float.
Why does a ship float in water whereas a name?
A ship floats in water as, after it displaces its weight, the level of water outside the hull is not high enough to pour over the gunnels (walls) of the ship and flood the inside of the hull.
How deep is the hull of a large ship?
Currently roughly 36 meters is the record. The depth of ships varies largely. Varying length, breadth, and weight, different hull designs, and even the salinity of the water itself, are all contributing factors. It depends on liquid displacement. It's all about buoyancy. An object submerged in a liquid is acted upon by two distinct forces; the downward force of gravity, and the upward force of buoyancy. If the object weighs more than the water it displaces, it will sink. If it weighs less than the water it displaces, it will float. If you could hang a ship on one side of a balance. You could add water to a container on the other side. Once they balanced, you would have the amount of water the ship will displace. If you poured that water into a container (shaped exactly like the hull of the ship), it would fill it to exactly the same depth at which that ship would float.
Why is ship not sink in sea?
Because the weight of the water it displaces is more than the weight of the ship itself.============================Because the weight of the water it displaces exactly equals the weight of the shipitself. Think of the water that was originally occupying the place where the ship nowis. That water didn't sink because it was supported by the overall pressure frombelow. Putting the ship there means that the force balance is precisely the same.Remember, compared with solid iron, a ship is mostly empty space.
What describes why a cruise ship floats?
It displaces an equal or greater amount of water than its own weight.
Why is ship floating on the water but it is made of metal?
Because the volume of water it displaces weighs more than the ship. Archimedes principle says that the upwards force on the ship is equal to the weight (mass) of fluid displaced - so the ship floats
