Expert Solution
Step 1

Fluid mechanics :

Fluid mechanics is the study of fluid dynamics at rest and in motion (liquids, gases, blood, and plasmas). Fluid mechanics has many applications, including mechanical and chemical engineering, biological systems, and astrophysics.

Given :

radius of the biosphere=0.985mnet weight of biosphere=198kgm=198×9.8m=1940.4 Nseawater density=1024 kg/m3
