three differences between buogant force and weight of the body
Answers
Answer:
The upward force exerted by water on any object is known as upthrust or buoyant force. The magnitude of buoyant force depends on the density of the fluid.
Buogant Force:
1. It's an upward force that opposes the downward force of gravity.
2. The magnitude of the buoyant force determines whether an object will sink, float, or rise when submerged in a fluid.
3. We can use the formula for hydrostatic gauge pressure P_{gauge}=\rho ghP gauge=ρghP, start subscript, g, a, u, g, e, end subscript, equals, rho, g, h to find expressions for the upward and downward directed pressures
Buogant Weight:
1. It's the principle that states the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g.
2. the object's weight is the same as the buoyant force acting on it, so the object floats. On the right, the object's weight is greater than the buoyant force acting on it, so the object sinks. Because of buoyant force, objects seem lighter in water.
3. This principle is useful for determining the volume and therefore the density of an irregularly shaped object by measuring its mass in air and its effective mass when submerged in water (density = 1 gram per cubic centimeter).
Hope it helps :)
