An object floats for three reasons. One, it is less dense than the solution it is floating in. Such as a piece of wood. Two, the object contains something that is less dense than what it is floating in. Such as a baloon. Three, the shape of the object is such that it does not have enough weight to displace enough of the solution to envelop the object. Such as with any seagoing vessell.

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 are the archemedes principle?
The bouyant force on an object is equal to the weight of the fluid the object displaces.
A rectangular barge 7 m long and 2 m wide floats in fresh water how much deeper does it float when its load is a 400 kg horse?
Consider the following - a submerged object displaces its volume, but a floating object displaces its weight. You also know (or can assume) the load is evenly distributed. So you can take the weight of the load (the horse) and apportion the displacement evenly across the boat. Now you are better prepared to calculate the answer.
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.
Is an object neutrally buoyant when it displaces an amount of water less than its own weight?
No, it sinks
What factors affect an objects ability to sink or float?
the water that it displaces (the amount of water it takes up in the water) is a factor. If the weight of an object is lighter than the weight of the amount of water it displaces, then, it floats. If the weight is higher than the weight of the water it displaces, then the object sinks.
What happends if the weight of an object is greather than the weight of the water?
I assume you mean "What happens if the weight of an object is greater than the weight of the water it displaces." If so, the answer is simple, it sinks. If an objects weighs less than the weight of the water it displaces, it floats.
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?
Do hydrometers float higher in liquids that are more dense or less dense?
An object floats when it displaces a volume of fluid that is equal to its total weight. The more dense (heavier per volume) the fluid is, the less the volume is that must be displaced to equal the weight of the object that floats in it.Therefore an object floats higher (is less submerged) in a denser fluid.
Why does an object seem lighter in water?
because of the upthrust in water it weighs less and floats. An object in water will recieve an upthrust equal to the weight of water it displaces . submarines when neutrally ballasted could hang by the periscope that is just under the water raise periscope sub sinks down as water covers periscope starts to rise again, Any floating object displaces its own weight of fluid.
What is law of flotation?
A floating body displaces its own weight of the fluid in which it floats.

Object displaces 16.5 mL of water what is the volume?
"Displacement" means pushing the water away from space where the object wants to be. If 16.5 mL of water is displaced, then the volume of the object must be 16.5 mL. At least the volume of the part of it that's down in the water, like if it's floating.
How does density affect buoyancy?
Ignoring shapes (using cubes), density (mass/volume) greater than "water" means it sinks. The floating object displaces its weight of the buoyant "object" (water, etc.)when it floats, but displaces its volume when it sinks.
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.
What will happen if the weight of an object is greater than the weight of the water that it displaces?
It will sink.
Which metal floats in water?
Sodium. Iron will float if it is a hollow structure according to Archimedes Principle that an object will float if it displaces an amount of water/fluid equal to the weight of the object. A ship will displace an amount of water equal to the weight of the ship, cargo and passengers combined.
