Buoyancy.
The object would float in the middle if it was in water.
The density of an object determines whether it will float or sink in water. If the object is denser than water, it will sink. If it is less dense, it will float.
An object will float on water if it has less density than the water.
I will assume that you are asking if it will float in water. That depends on the shape of the object and it's density, or you could say it depends on the effective density of the object where that takes into account any voids inside the object. If the material the object is made of is less dense than water, then the object will float. If the material the object is made of is denser than water and there are no internal voids, then it won't float. If the material the object is made of is denser than water but the object has sufficient internal voids so that its effective density is less than that of water, then it will float.
Buoyancy.
Density of the object and buoyancy of the water/liquid.
The "average" density of the object must be less than that of the water displaced.
the salt water is denser because of the salt
it increases the density of the water, making objects float easier. ex. the dead sea.
If the object does not quite float in water, adding salt to the water might make the object float, yes.
Objects float because the air in the object causes it to rise because it is less denser than water. Objects float better in salt water because the salt makes the water more denser helping even heavier objects to float. -Kimberly P.S. I learned all this in 4th grade!!!!!!!!!!!
it depends on what type of salt or what type of water like fluit water or fresh water
Many things can float in water. An object will float based on 2 main factors. They are density and shape. If an object is too dense, it will sink. But why would shape matter? The shape of the object affects how the water is displaced. If the weight of the water displaced is more than the weight of the object that is touching the water, the object will float. So the shape affects how much water is displaced therefore determines if an object will float.
The object would float in the middle if it was in water.
An object floats because the amount of water it displaces weighs more than the object floating. If the fluid in which something is floating weighs more than water the object will float higher. When salt disolves in water it makes the water heavier, causing the object to float higher. The floating object can be a boat, a piece of wood or a person, it doesn't really matter. The principles of physics are applied equally.
That depends what object you want to float.
