as relative density is directyy proportional to on surface area.... the iron ship being vast & having a huge surface area is able to float... whereas an iron ball being heavy & with less surface area sinks away..!
Ball bearings are typically made of steel, which is not a magnetic material. They will sink in water and not float because their density is higher than that of water. If exposed to a strong magnetic field, ball bearings made of magnetic materials like iron may be attracted to the magnet.
i believe you mean why does iron sink but the iron boat float. think about a balloon for a moment. if you take an empty balloon you can easily pull it under water, but if you fill the balloon with air and tie it shut, you cannot pull it under water. the same concept applies to the boat. The air inside and around the boat (yes, even if it is completely open with no roof) keeps it afloat
Iron fillings are denser than water, so they would sink when placed in water. Since water has a lower density than iron fillings, the fillings will displace the water and sink to the bottom.
No, iron is denser and heavier than polystyrene. An iron ball would weigh more than a polystyrene ball of the same size.
A hole. A hole in the ship's hull can cause it to take on water and eventually sink, even though the hole itself has no weight.
both a ball and a ship can sink.
iron is much denser than water. So, steel is denser, too, because it is made from iron.
To purposely sink a ship is to 'scuttle' the ship.
No old Iron sides was a ship used in the war of 1812. A British cannon ball hit the side of the ship on freshly cut replacement board. The board was strong enough to with hold the shock of the cannon ball. A sailor on the that ship called her "old Iron sides" from then on.
The ship is designed to be buoyant in the water. Buoyancy works when the water displaced by the object becomes equal to the force it is putting on the water
Because the ship contains a large amount of air in it. But iron nail doesn't have any space to contain air in it. Air is a lightest thing. That can't sink in water. This method is used in submarines to sink it. There is a tank in the submarine. When they need to sink it they fill the tank with water. To float it they use to fill the tank with air.
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
to sink a ship is 'couler un bateau' in French.
Captain Arthur Phillip's ship did not sink.
A Slip of the Lip - Can Sink a Ship - was created in 1943.
Ball bearings are typically made of steel, which is not a magnetic material. They will sink in water and not float because their density is higher than that of water. If exposed to a strong magnetic field, ball bearings made of magnetic materials like iron may be attracted to the magnet.
The iron ball will expands and the iron ball will be hot .
