How is the density of a floating object relate to the density of the fluid it is floating in?
If an item floats, Then it is less dense than the liquid it floats in. One can prove this using bernoulli's equation. To determine the weight of the floating object, take the volume of water displaced by the portion of the object below the fliud surface then multiply that by the density of the fluid. This process gives you the bouyant force on the floating object and therefore the weight. Then take that weight and divide it by the total volume of the. Object to get its density. Also note that if an item is suspended below the surface but. Above the bottom of the fluid body, then the item and fluid have equal density. If the item sinks to the bottom it has higher density than the fluid.
How do you calculate find the density of an object that floats?
If you can determine the volume fractions of the object that are above and below the water, then you can find the density of the object by multiplying the density of the fluid it floats in by the fraction of the volume that is below the surface of the liquid. Another, more complex way is to weigh the object alone then attach it to one arm of a balance to weigh the object when it is floating. As it floats it will displace an amount of liquid equal in weight to the total object. The decrease in weight will be proportional to the fraction of the object that is submerged. As an example: If an object weighed 100 grams out in the air but only required 20 grams to counterbalance its weight when it is floating, and the fluid it was floating in was water, then the density of the object would be (1 g/cubic centimeter)·(100-20)/100 = 0.8 g/cubic centimeter.
A piece of wood of relative density 0.25 float in a pail containing oil of relative density 0.81what is the percentage volume of the wood above the surface of the oil?
The percentage volume of the wood above the surface of the oil can be calculated by comparing the densities of the wood and oil. Since the relative density of the wood is lower than that of the oil, the wood will float with a portion of its volume above the surface. The percentage volume above the surface can be found using the equation: (1 - relative density of wood / relative density of oil) * 100%.
How do you know the density of an object if it floats on water?
If an object floats on water, it means its density is less than that of water. You can calculate the density of the object by comparing its weight to its volume, using the formula density = mass/volume. The density of water is about 1 g/cm^3, so if the object floats on water, its density will be less than 1 g/cm^3.
Would an object with a density of 1.0g per ml float sink or remain suspended in water?
An object of 1.0 g per ml will remain suspended in water because the density of water is 1.0 anything below 1.0 will float and anything above 1.0 will sink. There fore, 1.0 will remain suspended because that is the buoyant point.

What determines an object will sink or float?
The Density of the object as long as its .99 grams then it will float because the object has to have less density than water in order to rise above the water.
When is the pontoon is naturally stable?
When the center of buoyancy is directly above the center of gravity a floating object is stable.

What will happpen to an object that has less density than fresh water?
When you drop it into fresh water, it will bob up and down a few times,then come to rest partly submerged and partly above the water line.Anybody who sees it will exclaim "Oh look ! It is floating !"
How do you know the density of an object if it floats on water?
If an object floats on water, it means its density is less than that of water. You can calculate the density of the object by comparing its weight to its volume, using the formula density = mass/volume. The density of water is about 1 g/cm^3, so if the object floats on water, its density will be less than 1 g/cm^3.
Would an object with a density of 1.0g per ml float sink or remain suspended in water?
An object of 1.0 g per ml will remain suspended in water because the density of water is 1.0 anything below 1.0 will float and anything above 1.0 will sink. There fore, 1.0 will remain suspended because that is the buoyant point.
If an object has a volume of 50 Cm3 and a mass of 956G what is the density of the object?
It is 100 g/cm3 which is way above the most dense element!
Does the object float or sink the higher the density?
The the object you speak of is in water at approximately room temperature, then anything with a density above about 1 will sink; anything below 1 will float and anything at very close will be suspended in the water. So, to answer your question, high density equals sinking.
What does mass density and volume mean?
An object has a mass, say M It also has a volume, say V A useful relation between the above two is the ratio M/V which is defined as the density of the object. It is the mass of an object whose volume is unity. In solids and liquids, the density remains constant over temperature ranges and pressure ranges. But in gases the density is affected by temperature and pressure.
