Need typed format. 2. Suppose that particles move only by diffusion. Suppose that a number No of particles areinjected at z = 0 at time t = 0, and another N1 particles are injected at r = 0 at time tı > 0.Write down the function N(r,t) that gives the number density of particles at location r at time t.Hint: The PDE is linear so you can add solutions. Note that you will have different formulas for0t.

The differential equation for diffusion is of the form kδ2nx,tδx2=δnδt We solve this equation in the…
