Yes. Buoyancy force = weight of liquid displaced.If an object is less dense than the liquid, it floats. In this case no liquid is displaced. If the object is more dense than th4 liquid, it will sink displacing some liquid. the displaced liquid weight is the buoyancy force.
The more dense a fluid is the greater will be its bouyant force. The bouyant force will be directly proportional to the density of the fluid.
No, because density is a measure of matter that occupies a space, while buoyant force is the upward force that our body has.
Relative densities.
If the mass of an object remains constant, and the amount of space underwater it takes up (it displacement) increases, the buoyant force on the object will increase. The object will rise until it regains equilibrium, when it displaces the same mass of water as its own mass.
The amount of buoyant force is equal to the weight of the displaced water. The VOLUME of the displaced water is equal to the part of the solid that is submerged - thus, the buoyant force is equal to this volume, times the density of the water.
With less mass above sea-level to support, the buoyant root rebounds upward an amount that is exactly proportional to the density difference between the root and the underlying mantle.
Plenty of food
The increased amount of iron deeper into the mantle explains it.
It would stay the same
No change: Density is a property of the substance (physical property), which is not changed by the amount of substance.
The density of most substances will change if temperature is increased. The amount of change depends on the difference between the two temperatures.
The density does not change, as density is the amount of material in a given amount of space. But each piece has the same amount of space and material relative to each other.
Nothing happens if the volume is also allowed to increase.
The buoyant force is equal to the amount of water displaced. Multiply the volume of the object by the density of water - then convert that to a force (at about 9.8 newton/kilogram).
That depends on the amounts, of course - what exactly you are comparing. The buoyant force depends on the volume. For a certain volume of lead, there will be the same buoyant force as for the same volume of iron. On the other hand, since lead has a greater density, the buoyant force on a certain amount of MASS of lead will be less, compared to iron, since the same mass of lead will use up less volume.
