Twenty per cent (20%) of a rubber ball is floating above the surface of a pool of water. If water has a density of 1000 kg/m^3 and the ball has a mass of 3 kilograms, what is the volume of the ball?
Buoyancy is calculated by finding the weight of the fluid displaced by an object, which is equal to the buoyant force acting on the object.
Buoyancy is the upward force exerted on an object by a fluid. Weight is the force of gravity acting on an object. Buoyancy can either increase or decrease the effective weight of an object in a fluid.
The factors that affect buoyancy include the density of the fluid, the volume and shape of the object, and the force of gravity.
Buoyancy is directly related to the density of an object. If the object is more dense than the fluid, it will sink. If the object is less dense, it will float.
One example of buoyancy in real life is when a boat floats on water. The boat displaces a volume of water that is equal to its weight, allowing it to stay afloat. Another example is when a balloon filled with helium rises in the air because the helium is less dense than the surrounding air.
