The buoyant force keeps a submarine afloat.
If the weight of the submarine is equal to the upthrust acting on it, the submarine will float. This is due to Archimedes' principle, which states that an object will float when the buoyant force acting on it is equal to the gravitational force pulling it down.
The submarine will float when its weight is equal to the upthrust acting on it. This is because the upthrust force pushing the submarine upwards is equal to the weight of the water displaced by the submarine, resulting in a state of equilibrium where the submarine neither sinks nor floats.
The buoyancy force on a submerged submarine equals the weight of the water displaced by the submarine. This force acts in the opposite direction to the gravitational force, allowing the submarine to float or sink in the water.
When the weight of any object surrounded by fluid is greater than the buoyant force on it, it sinks. (The buoyant force is just the weight of the fluid that would be in that space if the submerged object were not there.)
If an object's weight is less than the buoyant force acting on it, the object will float. This is because the buoyant force acting upward is greater than the force of gravity pulling the object downward.
The submarine will sink if its weight is greater than the upthrust acting on it. Upthrust is the force pushing an object upwards in a fluid, such as water. When an object's weight is greater than the upthrust, it will sink.
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.
Yes, plastic balls can float on water because they are less dense than water. The buoyant force acting upward on the plastic ball is greater than the gravitational force acting downward on it, allowing it to float.
To rise again, the submarine's weight must be decreased. Air is pumped into the ballast tanks to force the water out. The buoyant force acting on the submarine now exceeds the submarine's weight. With positive buoyancy, the submarine rises. The less weight an object has the more its density decreases. Hope that kinda helps?
A submarine
the ability of the submarine to float
A submarine rotates its turbines in the opposite direction of normal rotation to cause water to be drawn towards the submarine. The force causing the mass to be moved toward the bow of the submarine is counteracted by the force drawing the submarine backwards.
