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)
An object in water ... whether floating or completely submerged ... is acted upon by two forces in the vertical direction: 1). its weight, directed downward, equal to its (mass) times (acceleration of gravity) 2). its buoyancy, directed upward, equal to the weight of the water that it displaces
