WebLet’s write Newton’s Second Law for a particle undergoing Brownian motion in water: \(F = m \ddot{x}\). (For simplicity we will work in one dimension, but the generalization to more dimensions is trivial. Just turn \(x\) and \(F\) into vectors.) In this equation, \(F\) is the force exerted on the particle by the surrounding water molecules ... WebFeb 2, 2024 · Biological Applications. 1) Fick’s First Law gives rise to the formulae: Diffusion Flux = -P (c 2-c 1), . where, P is the permeability, an …
WebFick’s second law. Fick's second law builds a relationship between concentration and diffusion flux under an unsteady state. Fick’s second law equation indicates the variable is changing with time, or the time to diffuse increases with the square of distance x. The equation for Fick's second law is as follows: d ρ d t = D d 2 ρ d x 2
