Is the variation in the density and composition of a body, where high density materials fall to the center of the body and low density materials float to the top?

The answer is differentiation. Differentiation is worried about things like rates and increasing velocities, slants and bends ect. Differentiation finds the immediate rate of progress of a capacity as for an autonomous variable. It is utilized when an amount demonstrates non-Linear variety. You can discover the speed of a molecule at a specific time by knowing the separation as an element of time.
