Question
Which of these objects will most likely float?A.A cruise ship that weighs 51,000 tons and would displace 50,000 tons of water if it were completely submergedB.An object whose volume is greater than its massC.A toy boat that weighs 2 pounds and displaces 1 pound of water if it is completely submergedD.A cruise ship that weighs 51,000 tons and would displace 70,000 tons of water if it were completely submerged
Solution
The object that will most likely float is D. A cruise ship that weighs 51,000 tons and would displace 70,000 tons of water if it were completely submerged.
Here's why:
The principle of buoyancy, also known as Archimedes' Principle, states that an object will float if it displaces a weight of fluid equal to or greater than its own weight.
A. The cruise ship weighs more than the water it displaces, so it would sink. B. The object's volume being greater than its mass doesn't necessarily mean it will float. It depends on the density of the object and the fluid it's in. C. The toy boat weighs more than the water it displaces, so it would sink. D. The cruise ship displaces more water weight than its own weight, so it would float.
