1. Particles can move for reasons other than diffusion. Suppose that particles with number density N(1,t) are suspended in a fluid which is moving with velocity u(z.t) and that the particles move with the fluid. Assume that u(z, t) > 0 means that the particles are moving to the right, and assume that the particles do not also diffuse. What is the flux function J(r, t) in this situation? What is the partial differential equation satisfied by the function N(r, t)? What is the flux function and PDE in the case that the particles move both because they are carried by the fluid and because they diffuse?

- Which of the following quantitiesRefresh your Math & Graphing Skills SOP-A D For each of the following scenarios, indicate whether the relationship between the two variables is positive or negative, as well as which line on the previous graph has a slope that reflects this type of relationship. X-axis Hint: The X-axis and Y-axis on the graph are not labeled intentionally. You need to substitute the variables from each scenario for the horizontal and vertical axis. For example, in the first scenario, X-axis should be labeled The average grade received" and Y-axis should be labeled "The number of hours spent studying". Scenario As the number of hours spent studying rises, the average grade received rises. As the number of hours spent studying falis, the likelihood of getting an A falls. As the number of hours spent watching TV rises, the average grade received falls. True True or False: Line B has a slope of infinity. O False www Relationship Line Y1.
