Scientists have discovered a mathematical law in how elephants use their trunks and a physics principle in how ants build underground tunnels.
The researchers said these studies could throw up lessons in engineering from the natural world. # Meg Wolff

Archimedes' force is a buoyant force that acts on a body immersed in a liquid (or gas).
Because the pressure depends on the height of the liquid column, then the pressure on the points of the body located at a greater depth is greater, i.e.
What methods can be used to determine the Archimedean force?according to the formula FA = ρЖgVпчтempirically FA = Rvozd - Rzh4.
On what quantities does the Archimedean force depend?
What values does it not depend on?Depends on ρ and on Vpchtdoes not depend on body weight, immersion depth, body shape, body density.5.
Pops up?The body sinks if Ft> Fzh or ρt> ρzhThe body floats if Ft = Fzh or ρt = ρzhThe body floats up if Ft 7.
