Density and upthrust
WebAnswer (1 of 6): Upthrust (better known as buoyancy) is equal to weight, but probably not the weight mentioned in this question. Buoyancy is upward force equal to the weight of … WebIf the upthrust is greater than the weight of the object, the object will rise up For an object to float, it must have a density less than the density of the fluid it is immersed in Worked example A steel cube with cross-sectional area of 2 m 2 is totally immersed in water.The scale balance reading is reduced when the cube is immersed.

WebFeb 1, 2024 · Buoyant Force. Buoyancy is a phenomenon due to buoyant force that causes an object to float. When you put an object in a liquid, an upward force is exerted on the object by the liquid. This force is equal to the weight of the liquid that has been displaced. The amount of liquid that has been displaced depends upon the density and the volume … WebOct 16, 2024 · ICSE IX Physics Upthrust in Fluids and Archimedes' Principle The mass of a certain material is 13.5 kg and its volume is 15×10 power-3 m3. a) calculate upthrust on …
WebIf the density of the object is greater than the density of the fluid, the object can never displace enough fluid to create an upthrust that will hold its weight up so it sinks. An object in a fluid experiences a pressure caused by both the fluid itself and the … According to Newton's first law of motion, an object remains in the same state of …
WebApr 4, 2024 · Since volume of solid immersed in liquid is equal to the volume of the liquid displaced, We get, upthrust = volume of solid immersed x density of liquid displaced x Acceleration due to gravity upthrust, So, we get upthrust U = V × D × g = 0.2 m 3 × 1 k g m 3 × g = 0.2 g f.
