Density and upthrust
WebOct 16, 2024 · Answer: (i) The density of a substance is defined as its mass per unit volume. Relative density of a substance is the ratio of its density to the density of water. (ii) The SI unit of density is kg/m 3 . Relative density is a unitless quantity. Question 26. Density of gold is 19300 kg m-3. Determine its relative density. Answer: 19.3 Question 27. WebJan 4, 2024 · If the density of the object is less than the density of the fluid, the upthrust will be the greater than its weight and the object will be pushed upwards towards the surface. As the object rises above the surface, how much fluid it displaces decreases.

WebDENSITY AND UPTHRUST The density of a substance is its mass per unit volume. Density = mass/volume ρ =m/v Where ρ (rho) is a Greek letter representing density. Its S.I. unit is kgm -3. WORKED EXAMPLE (1) An object weighs 0.08N in air and 0.01 N in a liquid of density 700kgm -3. Calculate the volume of the solid. SOLUTION ρ =mass/-volume WebUpthrust and density relationship. If the upthrust force is greater than the weight of the body, the object floats. If the fluid's density is greater than the substance's density, the …
WebThe mass of the fluid displaced = the volume of the object X the density of the fluid. Finding Upthrust. The weight of the fluid displaced is then calculated using the relationship: W = … WebUpthrust is the upward force acting on a body when it is partially or fully immersed in a liquid, it is also referred to as buoyant force. This concept …
WebUpthrust. Upthrust is a force which pushes upwards on an object submerged in a fluid i.e. liquids and gases. Also known as buoyancy force, upthrust is due to the difference … 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 …
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.
