The needle is solid, it's density higher than water's. The ship is hollow, its overall density lower than water's.
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 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.
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
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.
The steel ship has a lot of air inside. The nail is solid steel.
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 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.
A steel ship floats because of the principle of buoyancy. The weight of the water displaced by the ship is equal to the weight of the ship itself, allowing it to stay afloat.
A steel ship floats in water because of its shape and displacement. The design of the ship creates enough buoyant force to counteract its weight, allowing it to stay afloat. Additionally, the steel hull of the ship displaces enough water to keep it buoyant.
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.
The density of the VOLUME of the ship is less than the density of the water it displaces (pushes out of the way). While the steel of a steel hulled ship is denser than water, the steel plus the air enclosed by the steel is less dense.
because a ship has big volume and a coin has small volume hence the smaller the area the bigger the pressure,the smaller the area the big the volume
