How can matter be more or less buoyant?

it can be more or less buoyant be having more or less mass.i.e. lead will sink in water because the mass is higher and wood will float because it is lighter. the more mass the less buoyant, less mass means more buoyant.


What makes people buoyant?

People are buoyant in water because of the upward force exerted on them by the water, called buoyant force. This force is equal to the weight of the water the person displaces. People with lower body fat tend to be less buoyant, while objects with greater density than water will sink.


Does less ballast makes an object less buoyant?

No, the opposite.


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.


Is the buoyant force of water on lead greater than that on iron?

No, the buoyant force on lead is less than that on iron because lead is denser than iron. Buoyant force is determined by the weight of the fluid displaced, so the denser the object, the less fluid it displaces and therefore experiences less buoyant force.


Is there a buoyant force acting on you if there is why are you not buoyant up by this force?

Yes, there is a buoyant force acting on you when you are submerged in a fluid. However, whether you float or sink depends on the relationship between the buoyant force and your weight. If the buoyant force is greater than your weight, you will float; if it is less, you will sink.


An object will sink in water if its weight is less then?

the buoyant force acting on it.


If you climb a high mountain the buoyant force exerted on you by the atmosphere?

It is less.


An object is floating in a container of water?

The object is buoyant in water because the force of gravity acting on it is less than the buoyant force pushing it upwards. This buoyant force is equal to the weight of the water displaced by the object.


If the buoyant force is less than the weight of an object put in a fluid what will happen to the object?

If the buoyant force is less than the weight of an object placed in a fluid, the object will sink. This is because the force pulling the object down (its weight) is greater than the force pushing it up (buoyant force).


What is the relationship of buoyant force and density of liquid?

The buoyant force on an object submerged in a liquid is equal to the weight of the displaced liquid. The density of the liquid affects the buoyant force as denser liquids will exert a greater buoyant force on an object compared to less dense liquids.


As an object sinks deeper into fluid does buoyant force remain the same?

As an object sinks deeper into a fluid, the buoyant force decreases because the amount of fluid displaced by the object decreases. The buoyant force is equal to the weight of the fluid displaced by the object, so as the object sinks, it displaces less fluid and experiences less buoyant force.
