How does salt in water affect the boiancy of an egg?
as the salt dissolves in the water the water becomes more dense, so the egg will be more buoyant. (at least you tried to spell it correctly)
Is an object neutrally buoyant when it displaces an amount of water less than its own weight?
No, it sinks
How does buoyancy affect whether an object will sink or float?
If you just set the object in the water, the buoyant force never becomes greater than the object's weight. It sinks and sinks, displacing more and more water, building up more and more buoyant force, until the buoyant force is equal to its weight. At that point, the net force on it is zero, it stops sinking, and it stays right there (floating). The only way you can produce a buoyant force greater than its weight is to force it further down and hold it there. Since the buoyant force is greater than its weight, as soon as you let go, the net force on it is up, and it'll rise, partly out of the water until the buoyant force drops to equal its weight, and again ... it'll stay right there. So the answer to the question is: An object can't stay indefinitely in a position where the buoyant force is greater than its weight. If that happens, then it lifts some of itself out of the water, reducing the buoyant force, until the buoyant force is again just equal to its weight.
Why does a lemon seed rise and fall in a glass of sparkling water and not in still water?
In sparkling (carbonated) water, tiny bubbles of carbon dioxide can cling to a lemon seed (or anything else in the water) and when they do so, they make the seed more buoyant. The bubbles can also float away from the seed, leaving it in a less buoyant state. As a result, the seed can rise and fall.
Why would a raft float higher in the ocean than in a river?
Salt water contains solutes, and is heavier than pure water. This means that the raft, which will displace its own weight in water, will displace less water (and therefore not sink as far). The effect is that saltier water is more buoyant than less salty water.
By expanding and contracting their swim bladders fish can change their level in water How does this enable fish to become more or less buoyant?
(a) This helps them become more or less buoyant, because if they release the gas then they will sink making it more buoyant by getting air from the surface or from other bubbles it makes them less buoyant, making them float.
Why are some objects more buoyant then others?
Objects with a lower density than the fluid they are in will be more buoyant. This is because the buoyant force that an object experiences is equal to the weight of the fluid displaced by the object, so if the object is less dense, it will displace more fluid and experience a greater buoyant force.
Why is air more buoyant than water?
Air is more buoyant than water because it has a lower density. The density of an object determines its buoyancy - objects with lower density than the fluid they are in will float. Air is less dense than water, so objects are more likely to float in air than in water.
WHAT IS MORE BUOYANT PINE OR BIRCH?
The buoyancy of a wood species is determined by its density, with less dense woods being more buoyant. Pine is generally less dense than birch, so pine is typically more buoyant than birch. This is because buoyancy is directly related to the weight of the wood compared to the weight of the water it displaces.
What is the the force with which a more dense fluid pushes a less dense substance upward?
the buoyant force
Are oceanic or continental crusts more buoyant?
Continental crust is more buoyant than oceanic crust because it is thicker and composed mainly of less dense rocks like granite, whereas oceanic crust is thinner and denser due to its basaltic composition. This difference in density causes continental crust to float higher on the mantle, making it more buoyant.
Does less ballast makes an object less buoyant?
No, the opposite.
Are black people less buoyant?
Black children are 2.6 times more likely to drown than whites.
What makes some matter buoyant?
If the object or matter has a density lower than water does.
Is there buoyant force on an object at the bottom of the ocean?
As long as any part of the object ... doesn't matter how much ... is below the surface of the water ... doesn't matter how far ... there is buoyant force on it.
Is there buoyant force on an object at the bottom of an object?
As long as any part of the object ... doesn't matter how much ... is below the surface of the water ... doesn't matter how far ... there is buoyant force on it.
Why is wood is more buoyant than metal?
Wood is more buoyant than metal because wood has a lower density than metal. Buoyancy is a result of the object's density compared to the density of the fluid it is in. Since wood is less dense than metal, it displaces more water and experiences an upward buoyant force that keeps it afloat.
