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)
A completely submerged object always displaces its own?
mass of fluid, weight of fluid, density of fluid.
A completely submerged object displaces it own?
A submerged object will displace its own volume of the liquid it is submerged in.
What effect does the density of liquid have on the buoyancy of an object?
An object with lower density than the liquid will float, one with more density will sink. Anything with the same density will stay at the depth where it is placed. If it is placed half submerged it would sink until submerged.
How many fluid does a submerged object displace?
The amount of liquid a object displaces is directly proportional to the density of the object
Can density tell us what percentage of a floating object will be above the water?
Yes, because density is measuring the volume of the object. So it shows how much percent of the object is submerged.
If an object has the same density as the fluid it is submerged in the object will always?
Will always float with the top surface level with the water
How do you find density of irregular shape?
Measure the displacement of water when the object is submerged in water. This gives the volume ; then weigh the object and divide the weight by the volume to get the density.
How do you find density of an irregular shape?
Measure the displacement of water when the object is submerged in water. This gives the volume ; then weigh the object and divide the weight by the volume to get the density.
If the solid is not completely submerged in the water Explain how this technique error affects the reported density of the solid?
You wouldn't get the right reading of volume of the object, so you're density calculation would be off.
How does the volume of completely submerged object compare with the volume of water displaced?
They are equal.
When will an object float on a fluid's surface?
To be straight in answering,I would write that if that particular object has its density nearly equal to the density of fluid displaced by its submerged part then only the object will be likely to float in the fluid.
Will an object that has a density of 0.5gmcubed will it float or sinkfloat or sink?
Any submerged object that have less dense than the water it will float. Therefore your submerged object probably will float because it has less dense than the water. I hope my answer helped you.=)
