The short answer is that we need to use the volume of the fluid displaced V f l u i d in the formula because the displaced fluid is the factor that determines the buoyant force. What's the longer answer?
The mass of the displaced fluid can be expressed in terms of the density and its volume, m = ρV. The fluid displaced has a weight W = mg, where g is acceleration due to gravity. Therefore, the weight of the displaced fluid can be expressed as W = ρVg .
Now use the following formula to calculate the volume of the object. Volume (object) = Volume (water + object) – Volume (water) Volume (object) = Vol2 – Vol1 Volume (object) = (30 – 13.33)
25 kwi 2017 · Many chemistry and physics experiments involve collecting the gas produced by a chemical reaction and measuring its volume. Water displacement represents one of the easier methods to accomplish this task.
4 dni temu · Archimedes’ principle, physical law of buoyancy stating that any body submerged in fluid (gas or liquid) at rest is acted upon by an upward, or buoyant, force, the magnitude of which is equal to the weight of the fluid displaced by the body. Learn more in this article.
Students use the water displacement method to find the volume of different rods that all have the same mass. They calculate the density of each rod and use the characteristic density of each material to identify all five rods. Then students consider the relationship between the mass, size, and arrangement of atoms to explain why
21 cze 2016 · Knowledge of displacement volumes is required to calculate the volume of a solvent to add to a known amount of solid in order to obtain an exact volume of solution. The following example may help to explain the concept of displacement volumes.
