An object has a weight of 14n in the air it apparently weighs only 3n when it is completely submerged in water what is the density of the object?

Since the DENSITY of WATER = 1, and the Weight is 14 Newtons (in air) and 3 Newtons (Submerged in Water) we can figure the Density of the Object by the following:
N = kg·m/s2
14 N = (Mass of Object) x 9.81 m/s2
(Mass of Object) = 14 N / 9.81 m/s2
(Mass of Object) = 1.427 kg
And Since IN WATER the Object is 3 Newtons:
3 N = (1.427 kg x 9.81m/s2 ) / (Density of Object)
3 N = (14 N) / (Density of Object)
Density of Object = (14 N) / (3 N)
Density of Object = 4.6667

How does the volume of completely submerged object compare with the volume of water displaced?
They are equal.
What are 2 ways to find the volume of an object?
Derive from measurements of length, breadth, height, radius, diameter etc. Measure the volume of displaced liquid when the object is submerged. If the object is of a material of known density (or specific gravity), weigh it and calculate volume from volume = mass/density.
The volume of a submerged object is equal to of the liquid displaced?
yes
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.
What is the formula you use to calculate the density of an object?
Object's density = (its mass) divided by (its volume)
What is submerged density?
Submerged density is the density of an object when it is immersed in a fluid. It takes into account the volume of the object that is submerged in the fluid. This can be calculated using the formula: (density of object * volume of object) / (volume of object - volume of displaced fluid).
A completely submerged object always displaces its own?
mass of fluid, weight of fluid, density of fluid.
Why does the object apparently loss weight when completlely submerged in water?
An object will appear to lose weight when completely submerged in water due to the buoyant force acting on it. This force is equal to the weight of the water displaced by the object, causing it to feel lighter in water compared to in air.
When an object is said to be immersed in water does this mean it is partially submerged or completely submerged?
When an object is immersed in water, it means it is completely surrounded or covered by the water.
How does the ml of a completely submerged object compare with the ml of water displaced?
The milliliters of a completely submerged object is equal to the milliliters of water displaced. This is in line with Archimedes' principle, which states that the volume of water displaced by an object is equal to the volume of the object submerged.
How does the buoyancy of an object depend on it's density?
The buoyancy of an object depends on its density compared to the density of the fluid it is submerged in. If the object's density is less than the fluid, it will float; if the density is greater, it will sink. The lower the density of the object, the higher the buoyant force acting on it.
An object in a fluid will float if?
the buoyant force acting on the object is greater than its weight. This occurs when the density of the object is less than the density of the fluid it is submerged in.
What are the two ways to measure the density of an object?
The two ways to measure the density of an object are by using its mass and volume. You can calculate density by dividing the object's mass by its volume, or by measuring the displacement of water when the object is submerged in it.
What effect does the density of liquid have on the buoyancy of an object?
The density of the liquid affects the buoyancy of an object by determining how much force the liquid exerts on the object. If the liquid is more dense than the object, the object will float. If the object is more dense than the liquid, the object will sink.
When the buoyant force on a submerged object is equal to the weight of the object how do the densities of the object and water compare?
When the buoyant force on a submerged object is equal to the weight of the object, the density of the object is equal to the density of the water. This is because for the buoyant force to equal the weight of the object, the object displaces its own weight of water, which can only happen if the object and the water have the same density.
What property of an object determines the strength of buoyant force that will be exerted on it when submerged in water?
The buoyant force exerted on an object submerged in water is determined by the object's volume and the density of the fluid it is in. Specifically, the buoyant force is equal to the weight of the fluid that the object displaces.
If the solid is not completely submerged in the water Explain how this technique error affects the reported density of the solid?
If the solid is not completely submerged in the water, the volume of water displaced will be underestimated. This error will lead to a lower apparent volume, resulting in a higher reported density of the solid than the true value.
