buoyant force acts on the object from its bottom and push it outside..the magnitude of the buoyant force acting on the object will b equal to the weight of displaced water..

∙ 12y agoIf the object floats, then its vertical acceleration is zero. That tells us that all vertical forces
on it add up to zero. We know that its weight, acting downward, is 340 N, from which we
can calculate that the buoyant force on it, acting upward, must also be 340 N.
The buoyant force is equal to the weight of the displaced fluid.

What density are objects that sink in water?
It's greater than the density of the surrounding fluid medium. For example, a balloon filled with air sinks in air -- falls to the ground -- but floats in water. For water-tight objects, it is the average density that matters. The buoyant force acting on an object submerged in water is equal to the weight of the water displaced by the object. If the object weighs more than the weight of the water it displaces, it will sink, because the buoyant force will be less than the object's true weight. If it weighs less than the weight of the water displaced, it will float. If it weighs exactly the same as the water it displaces, it is said to have neutral buoyancy and will appear to be and behave as if it were weightless. In other words, its apparent weight will be zero. As discussed in the previous paragraph, if a submerged object sinks, we know it weighs more than the water it displaced. We can therefore conclude that it is denser than water.
What scientific rule states that the buoyant force an an object is equal to the weight of the fluid displaced by the object?
Since the object is submerged, we know that the buoyant force is not sufficient to overcome the weight of the object, otherwise it would be floating rather than being submerged. Therefore, the buoyant force is equal to the weight of the displaced water, not the weight of the object itself.
How is buoyant force and displacement related?
buoyant force is the result of the displacement of the fluid an object is in. if a fluid is displaced by the volume of an object, the weight of the fluid being displaced is pushing up on that object
What does the weight of an object that floats have the same value as?
The weight of the substances are largely immaterial. What matters is the density. Assuming fresh water to have a density of 1.0 anything with a lighter density will float in it. For example, oil generally has a density of about 0.8, so it floats in water. Concrete has a density of about 2.4, so it sinks. http://physics.about.com/od/fluidmechanics/a/commondens.htm
What happens to the body when the upthrust is less than the weight of the object'?
An object that is COMPLETELY submerged in water has its Upthrust equal its weight, but it doesn't necessarily float, an object could be at the rock-bottom of the ocean, and it would still have its upthrust equal to its weight. This is because the upthrust is equal to the weight of the fluid displaced, and so while the objects volume remains constant, and assuming the density of the fluid it displaces is constant.. The upthrust remains constant, this is unless the object compresses and has its density altered.. I know I didn't directly answer your question, but I hope this helps.. Even if a little.
Would an object of 3.7 cm float why or why not?
Floats when it displaces its weight of water; sinks when it's displaced water weighs less than the object. Huh?
Is it true that If an object floats the volume of the displaced water is equal to the volume of the portion of the object that's underwater?
the weight of the displaced water is equal to the weight of the object
Which object weighs more a can that floats or a can that sinks?
It is impossible to tell; whether an object floats or sinks depends on its density, not on its weight.
If an object floats the volume of displaced water is equal to the volume of what?
Look at the LAST WORD of the question, they switch it sometimes if it is: Underwater than it is TRUE, If it's Surface of the water than it is FALSE ~
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 is when an object is placed in a fluid and the object weighs less by an amount equal to the weight of the displaced fluid?
"buoyancy"
When an object is placed in a fluid the object weighs less by an amount equal to the weight of the displaced fluids?
This is corrent

This is corrent
An object that weighs 340 N is sinking. What is the weight of the displaced water?
340 N
When an object is placed in a fluid the object weighs less by an amount equal to the weight of displaced fluid is?
this is Archimedes' Principle
Is gravitational force equal to the weight of the fluid displaced by an object?
No. Gravitational force is directed DOWNward. The weight of the displaced fluid is another force, directed UPward. If they happen to be equal, then the net force on the object is zero and it floats. But they don't have to be equal.
