WebF B = w fl, where F B is the buoyant force and w fl is the weight of the fluid displaced by the object. This principle is named after the Greek mathematician and inventor Archimedes (ca. 287–212 BCE), who stated this principle long before concepts of force were well established. Figure 14.21 (a) An object submerged in a fluid experiences a ... WebSep 12, 2024 · If the buoyant force is greater than the object’s weight, the object rises to the surface and floats. If the buoyant force is less than the object’s weight, the object …

WebArchimedes' Principle. The buoyant force on a submerged object is equal to the weight of the fluid displaced. This principle is useful for determining the volume and therefore the density of an irregularly shaped object by … WebThe formula can calculate the volume of the fluid; Vf=l×w×h; where l is the length, w is the width, and h is the height. By substituting the value of density and volume, the buoyant force is calculated by the formula, F b =ρgV. For example, An object of mass 4kg is submerged in a fluid medium whose volume is 8m3 they how to calculate buoyant ... 79公斤是多少斤
