Therefore, the net buoyant force is always upwards. The mass of the displaced fluid is equal to its volume multiplied by its density: mfl=Vflρ m fl = V fl ρ . Archimedes principle: The volume of the fluid displaced (b) is the same as the volume of the original cylinder (a).

## How does Archimedes Principle explain whether an object will float or sink in water?

If the buoyant force is greater than the object’s weight, the object will rise to the surface and float. If the buoyant force is less than the object’s weight, the object will sink. Archimedes’ principle states that the buoyant force on an object equals the weight of the fluid it displaces.

What are the applications of Archimedes Principle?

Applications of Archimedes’ Principle

• Ships. Have you ever wondered that why an iron nail sinks in the water but large ships do not?
• Beach Balls. Beach balls are filled with air only, so they have a very small weight, hence they do not displace much water.
• Submarines.
• Floating.
• Hydrometer.
• Swimming.
• Hot Air Balloon.
• Lactometer.

Why do humans float in water?

A human submerged in water weighs less (and is less ‘dense’) than the water itself, because the lungs are full of air like a balloon, and like a balloon, the air in lungs lifts you to the surface naturally. If its less dense than water, then it will float.

### Which is the correct equation for archimedes’principle?

In equation form, Archimedes’ principle is where FB is the buoyant force and wfl is the weight of the fluid displaced by the object. Archimedes’ principle is valid in general, for any object in any fluid, whether partially or totally submerged. According to this principle the buoyant force on an object equals the weight of the fluid it displaces.

How is the Archimedes principle related to Pascal law?

Pascal law. Archimedes law. Archimedes principle states that When an object is totally or partially immersed in a liquid, an upthrust acts on it equal to the weight of the liquid it displaces.

How is the Archimedes law related to buoyant force?

If only a part of the volume is submerged, the object can only displace that much of liquid. In simple form, the Archimedes law states that the buoyant force on an object is equal to the weight of the fluid displaced by the object. Mathematically written as: The mass of the liquid displaced is. Thus the weight of that displaced liquid is:

#### How can Archimedes’s law be used to determine density?

Archimedes’s law is also helpful to determine the density of an object. The ration in the weights of a body with an equal volume of liquid is the same as in their densities. Here w 2 is the weight of the solids in a liquid.
