Question

we have a quantity in bottle of volume 350 m (cube) whit an occupying mass of 100kg . calculate the density, relative density and state if it will float in water or sink​

Answer 1

Answer:

The space it occupied is filled by fluid having a weight wfl. This weight is supported by the surrounding fluid, and so the buoyant force must equal wfl, the weight of the fluid displaced by the object. It is a tribute to the genius of the Greek mathematician and inventor Archimedes (ca. 287–212 B.C.) that he stated this principle long before concepts of force were well established. Stated in words, Archimedes’ principle is as follows: The buoyant force on an object equals the weight of the fluid it displaces. In equation form, Archimedes’ principle is

FB = wfl,

where FB is the buoyant force and wfl is the weight of the fluid displaced by the object. Archimedes’ principle is valid in general, for any object in any fluid, whether partially or totally submerged
