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.

How are distance or displacement similar and different?
Displacement is the distance that something has moved. You could have distances between two different objects, and the distance could be constant if the objects do not move. Displacement is always for the same object, and it has to have moved.There is one other sense for the word displacement: it is the amount of liquid that an object displaces (takes the place of) when the object is placed in the liquid. For example, when a boat floats in the water, it displaces 1 gallon of water for every 8 pounds the boat weighs. If an object sinks, it is because it displaces water that weighs less than the object does.
What is the law of buoyancy?
Buoyancy is the rising of an object through a liquid such as water due to the object being less dense than the liquid. Density is the the mass of an object divided by its volume. Density is often expressed in grams/cm³. For a full explanation of how the buoyancy principle works go to the related question "What is the buoyancy principle?" in the Related Questions section below.
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 will happen if a solid object immersed in a fluid weighs more than the volume of the fluid displaced by the solid?
Then the solid object has a greater density and will sink.
Why do corks float in water?
Any object placed in water will be pulled down into the liquid by gravity. No surprise there. But an object less dense than water will only be pulled down until the object displaces an amount of water equal to its own mass. Then it will float. The water will be pushing up equal to the force of gravity pulling down - an equilibrium. Any object that weighs less than its own volume of water will float. It's lower overall density will result in buoyancy.
Why is the reason an object floats in water?
If the volume of liquid the object displaces weighs more than the object, the object will float. The principle is buoyancy or specific gravity.
An object weighs 20 N It displaces a volume of water that weighs 15 N?
You haven't asked a question. So I'll ask one using your data, and then answer it. Q: What is the apparent weight of the object when it's completely submerged ? A: 5 N.
How balloons and blimps are able to fly in oceans of air?
Balloons float because of the same principal as how ships float: bouyancy. A ship displaces a volume of water. If the ship's weight is less than the volume of water that it displaces, then it will float. Same is true for a balloon. It displaces a volume of air. If the Hydrogen or Helium in the balloon weighs less than the volume of air it displaces, then it will rise.
When does an object sink in water?
An object will sink when it weighs more than the water it displaces (around 62 pounds per cu foot)
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?
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.
Is the larger the volume of an object the more it weighs true?
Yes
What weighs volume?
There isn't an actual machine that weighs volume, per-say. The weight of an object can be found, then using an equation or calculator, the weight can be converted into volume.

Does volume tell us how much matter weighs?
Volume "tells" us how much an object can be filled with or how much an object can hold.
