the force of gravity
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.
1 newton.
The buoyant force acting on the balloon is equal to its weight, which is 1N. This is because the balloon is in equilibrium, with the buoyant force balancing the weight of the balloon, so it does not move up or down.
The buoyant force on the object is equal to the weight of the water displaced by the object. Using the density of water (1000 kg/m^3), the volume of the object, and the acceleration due to gravity (9.81 m/s^2), we can calculate the buoyant force to be 0.1 N.
The buoyant force acting on the one-ton ship is equal to the weight of the water displaced by the ship. Since the ship floats, the buoyant force is equal to its weight, which is 1 ton (2000 pounds) in this case.
There is no difference.
The buoyant force on both blocks would be equal because it depends on the volume of the object displaced in the water, not the material it's made of. Both blocks would displace the same volume of water, experiencing the same buoyant force.

The upward buoyant force is simply equivalent to the weight of an amount of the fluid that would occupy the same space (same volume). The total upward force on the body, if freely floating, would be found by subtracting the downward force of the body's own weight. So for example, the buoyant force on a balloon filled with air submerged in water would be equal to the weight of the same-size balloon filled with water suspended in air.
upthrust=buoyant force=weight of the body immersed in d liquid so gravity and mass is a cause of upthrust as weight of a body=mass* gravity
The mass of the rock doesn't make any difference. Anything with a volume of 21 L, when it'scompletely submerged, displaces 21 L of water, and produces a buoyant force equal to theweight of 21 L of water.21 L of water has a mass of 21 Kg. Its weight is (MG) = (21 x 9.8) = 205.8 Newtons = 46.3 pounds. (rounded)
ANS1:Because of the natural buoyancy water provides steel actually weighs less in water. so 1 million pounds of steel in water would weigh only 500,000 pounds. Cheers!! ANS2:Bull. Answer 1 is a soup sandwich. The earth is still pulling the steel towards it with the same force. That force is its weight. That the water is also being pulled toward the earth and causes the buoyant upward force on the steel does not make the steel's weight less. That is like arguing that a hunk of steel is weightless because the floor is pushing against it as hard as it is pushing against the floor or arguing that a steel-hulled ocean liner has no weight because it floats in water. The steel will still have the weight of 1 million pounds-force.Since the specific gravity of steel is 7.8, the upward buoyant force will be 1/7.8 of its weight. If you insist on using pounds to measure weight, the upward buoyant force would be 128,000 pounds-force. You could subtract this from the 1 million pounds-force of the steel to get 872,000 pounds-force. You could call this its effective weight or net downward force if you want to make the point that that force is what is pressing on the bottom of the body of water.This is probably the answer you should put on your homework if you are a student in a U.S. public school. If you put anything else down, you will likely confuse your teacher especially if you try to argue the difference between pound-force, pound-mass poundals, and slugs.ANS3ALOT!
