If an object weighs 20 n it displaces a volume of water that weighs 15 n What is the bouyant force of the object?
According to Archimedes principle...An object immersed in water experiences a force equal to the weight of the volume of liquid displaced by it. Here the weight of liquid displaced is 15n. So, the upward buoyant force experienced by that object is 15n.
What makes an object seem to weight less when you hold it in a pool of water?
This phenomenon is called buoyancy and is caused by the object displacing water equal to its volume. If the weight of the object is less than the weight of this displaced water, then the object has positive buoyancy and will float. If the weight of the object is exactly equal to the weight of this displaced water, then the object has neutral buoyancy and thus be weightless. If the weight of the object is greater than the weight of this displaced water, then the object has negative buoyancy and will sink but it still weighs less than it did out of the water.Just remember buoyancy only affects the weight of the object, it has no effect on the mass of the object which remains constant in or out of water.
For an object to sink in a fluid there must be an unbalanced force?
The weight of the fluid displaced has to equal the object's weight for the object to float. If there is not a balance between these two forces then the object will sink.
Principles which helps a ship float?
Archimedes' principles: -- An object in a fluid experiences an upward force equal to the weight of the displaced fluid. -- A sinking object displaces its volume. -- A floating object displaces its weight.
If an object float the volume of the displaced water is equal to the volume of the whole object?
False
How an object float in a liquid with illustration?
When the displaced fluid has a mass equal or greater than the mass of an object placed in the fluid, the object will float.
What is Archimedes princible?
Archimedes principle states that : The force of buoyancy is equal to the weight of the displaced water. If the weight of the water displaced is less than the weight of the object , the object will sink. Otherwise the object will float , with the weight of the water displace equal to the weight of the object.

What can float in the water?
Many things can float in water. An object will float based on 2 main factors. They are density and shape. If an object is too dense, it will sink. But why would shape matter? The shape of the object affects how the water is displaced. If the weight of the water displaced is more than the weight of the object that is touching the water, the object will float. So the shape affects how much water is displaced therefore determines if an object will float.
Explain Archimedes' principle?
Archimedes' Principle relates the weight of a fluid displaced to the object placed in the fluid. If the weight of the fluid displaced is less than the object's weight ,then the object sinks. When the weights of the object and displaced water are equal, the object will float.

The weight of the fluid displaced has to equal the object's weight for the object to float. If there is not a balance between these two forces then the object will sink.
Why can't heavy objects float without salt?
They can float without salt - It's the ratio of water displaced by the object in relation to its weight of the object that allows it to float - not the salt content of the water.
What force cause objects to float when the weight is greater than a buoyant force?
If the weight of an object is greater than its buoyant force, then it will not float - it will sink.
When buoyant force due to water is greater than the weight of the object?
In that case, such an object will float.
Can a concrete boat float?
Yes- because they are not a solid block of concrete- they are hollow with a large air space. The weight of the water displaced is greater than the weight of the hollow concrete hull, and it will float.
