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.
A ship made of steel floats because it has a hollow structure that displaces enough water to create buoyant force greater than its weight. A needle sinks because its density is greater than that of water, so it does not displace enough water to generate enough buoyant force to support its weight.
The steel ship floats because of its shape and displacement of water, creating an upward buoyant force greater than its weight. The steel needle sinks because of its small volume and weight relative to its size, leading to a downward force greater than the buoyant force acting on it.
A ship floats because it displaces a volume of water that is equal to the weight of the ship. The shape and material of the ship help distribute its weight and create buoyancy. On the other hand, a needle sinks because its weight is greater than the buoyant force it generates in water due to its small size and density.
A needle doesn't float because there is very little air in a needle. Metal is much more dense than wood, which is what most boats are made of. When a boat is made of metal, there are air stores inside of the boat that keep it afloat.
A piece of stone sinks in water because its density is greater than that of water, leading to a net downward force. In contrast, a ship with a large weight can float because its shape and design displace enough water to create an upward buoyant force that exceeds its weight, as per Archimedes' principle of buoyancy.
The needle is solid, it's density higher than water's. The ship is hollow, its overall density lower than water's.

a ship wreck is when a ship sinks and floats to the bottem of the ocean were it is filled with water and creatures of the sea.

Ultraoversimplifying it, the coin is solid metal all the way through and weighs more than its volume of water, the ship has a large space filled with air inside it resulting in the weight of the ship and cargo being less than the weight of the volume of water it occupies.This is called buoyancy: the coin has negative buoyancy and sinks, the ship has positive buoyancy and floats.
Density of a steel ball is greater than the den. Of h2o - it sinks similarly den. Of a toy ship is less than the den. Of h2o - it floats
AnswerThe air in the ship PLUS the weight of the ship must just equalthe weight of the water displaced (pushed out of the way)by the hull of the ship.The pin lacks the air.
An object will sink if its density is greater than that of water (or another liquid in which it is placed). If its density is less, it will float. In the case of the ship, the air in the ship helps reduce the total density.
A needle doesn't float because there is very little air in a needle. Metal is much more dense than wood, which is what most boats are made of. When a boat is made of metal, there are air stores inside of the boat that keep it afloat.
a ship
Weight of ship = weight of (displaced) water.
