What would best described buoyant force of air be greatest?
The buoyant force of air is greatest when an object is fully submerged in the air. This is because the volume of air displaced by the object is at its maximum, creating the greatest upward force. The buoyant force decreases as the object is lifted out of the air, until it reaches a point where the object is no longer displacing enough air to experience a significant buoyant force.
What term would the buoyant force of air be greatest in?
The same for all.
What is an example of when the buoyant force of air is greatest?
an airplane
For which of these would the buoyant force of air be greatest a bird hotair ballon an airplane?
The buoyant force of air would be greatest for a hot air balloon because it relies on the principle of buoyancy to stay aloft. The heated air inside the balloon is less dense than the surrounding air, creating a greater buoyant force to lift the balloon. A bird and an airplane rely on aerodynamic lift generated by their wings to stay airborne, rather than buoyancy.
Would an airplane of an buoyant force of air be greatest?
An airplane experiences lift due to the difference in air pressure above and below its wings, not buoyant force like a balloon or boat in water. The lift force is greatest when the aircraft is at the optimal angle of attack which allows for maximum lift to overcome weight.
Why does solid body weigh more in air than when immersed in a liquid?
the buoyant force of the liquid on the solid is more than the buoyant force of the air on the solid.
What buoyant force is exerted on a toy balloon with a volume of 6000ml by the air surrounding the balloon?
The buoyant force exerted on the toy balloon by the surrounding air is equal to the weight of the air displaced by the balloon. This force is calculated using Archimedes' principle, which states that the buoyant force is equal to the weight of the fluid displaced by the object. The buoyant force is counter to the force of gravity and will keep the balloon floating in the air.
What is the buoyant force of a hot air balloon?
The buoyant force on a hot air balloon is equal to the weight of the air displaced by the balloon. When the air inside the balloon is heated, it becomes less dense than the surrounding air, causing the balloon to rise. The buoyant force allows the balloon to float in the air.
Why is a buoyant force not present in air?
A buoyant force is not present in air because air is less dense than objects that float in it, so there is no upward force pushing objects up like in water.
Object Weights more in air water vacuum or hydrogen?
An object weighs less in air compared to its weight in vacuum or hydrogen, as air exerts a buoyant force on the object. The object weighs more in water than in air due to water's buoyant force. In a vacuum or hydrogen, where there is no buoyant force, the object's weight would be the same as its actual weight.
How much buoyant force acts upon a balloon that weights 1 N?
The buoyant force acting on a balloon is equal to the weight of the fluid it displaces. Using the principle of Archimedes, the buoyant force would be equal to the weight of the air displaced by the balloon, which would be equal to 1 N.
Is there a buoyant force acting on you at this minute?
Yes, there is a buoyant force acting on you at all times, even when you are not in water. This force is due to the displacement of air by your body, which creates a buoyant force that is usually negligible compared to when you are in water.
