Yes! If you had studied physics, for example, you would know what makes
things float in a fluid: buoyancy force, caused by differential in fluid
pressure. In a centrifuge, this buoyancy force is centripetal and the
differentiation is magnified.

Not at all! All this is gone over in introductory physics and you even have
a book on it! Look at how much you’ve missed by not reading!!
