1 the predation p(n) on a population n(t) is very fast and a model for the prey n() satisfies n2 dn dt p 1-exp where r. k, p and a are positive constants. by an appropriate nondimensionalisa- tion show that the equation is equivalent to du dt it where r and q are positive parameters. demonstrate that there are three possible nonzero steady states if r and q lie in a domain in r. q space given approximately by rq 4. could this model exhibit hysteresis?

Choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. a 1.0 kg block is placed on top of a 2.0 kg block. a horizontal rope pulls the 2.0 kg block across a frictionless floor with a force of 21.0 n. the coefficient between the two blocks is 0.75. does the 1.0 kg block on top slide?
