Even though a brick weighs less than a metal-hull ship a brick in a bathtub sinks but a metal-hull ship in the ocean floats why?
Density.
Why does a ship made of steel float while a needle sinks?
A needle is fully metal whereas a ship is hollow so it floats
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
How do you know the density of an object if it floats on water?
You do not. A metal ship, with density well above that of water, will float.
What would happen to an objects density if you multiplied the amount of objects?
Nothing at all. The density of one penny is the same as the density of a truckload of pennies, or of a cargo-ship-load of the metal that's used to make pennies out of.
Can 10 people make a real pirates ship?
if you know how to ship make a metal boat then you will know how to make a wooden pirate ship.
How does coating with another metal prevent corrosion?
when you coat a metal in another metal you are protecting the inside metal. The metal metal that is being used as a coat must be more corrosive than the 1st metal. For example iron can be coated in zinc because zinc is more corrosive than iron. This is common on a ship, the iron hull is coated with blocks of zinc which will act as a barrier and will corrode instead of the iron. The zinc blocks must be renewed after a period of time however. Other ways of stopping metals from corroding include, chromium plating, coating in paint, oil or plastic.
What is ratguard?
A cone shaped piece of metal fitted to a rope or hawser to prevent rats from boarding a ship while moored to the dock.
Kinds of metal in building a ship?
Usually steel or Aluminum but special paint and coating should be applied to prevent rusting from the water.
To prevent a ship from tiping?
to prevent a ship from tipping it should way 3 million pounds
How do sacrificial metals protect ship's hulls?
Sacrificial metals work in accordance with the "galvanic series" - the potential for current flow from one metal to another. If you put two metals in an electrolyte, of which seawater is a good one, the less noble or "more anodic" metal will corrode and save the more noble or "more cathodic" metal from corroding. Zinc, being both highly anodic and very cheap to purchase, is the standard sacrificial anode on ships.
Why does a metal ship flow on water?
Because in the ship has more air than the water.Therefore water has more density than the metal ship which contains more air.
Scuttling a ship?
That is where the crew sinks their own ship. It was done to prevent the ship from falling into enemy hands.
How did Columbus prevent mutiny on his ship?
dont no
What is an Ironclad battleship?

What is a heavy piece of metal for lowering into the water to keep a ship from moving?
An anchor is a heavy piece of metal for lowering into the water to keep a ship from moving.
