5. Now that we've talked about the behaviour of very large capsules, let's consider very small capsules. (a) (1 point) Evaluate lim Apart (b) (1 point) Explain, using (a), why the mathematical model we've been using doesn't match well with reality for very small capsules. (c) Suppose the density (mass per unit volume) of our capsules is better expressed as p(surface area) volume if the capsule is above a certain size is the capsule is less than or equal to that size for some constant c, where c is the density (mass per unit volume) of the material making up the capsule. i. (1 point) Explain why this formula makes sense. ii. (1 point) Using this description, will very small capsules (of any shape) float, or sink
