3. [15 marks] A new tropical disease has emerged on an isolated island where the population is 1000. Observation shows that the disease has the interesting property that there needs to be a minimum number of infected individuals before it can spread through the population. The disease spreads according to the differential equation dD/dt= 0.001(D - 100)(1000 - D) where D(t) is the number of infected people on the island and t is measured in days. (a) Find all the...

An aluminum transmission line with a diameter of 20 mm has an electrical resistance of R'elec= 2.636 × 10-4 Ω/m and carries a current of 700 A. The line is subjected to frequent and severe cross winds, increasing the probability of contact between adjacent lines, thereby causing sparks and creating a potential fire hazard for nearby vegetation. The remedy is to insulate the line, but with the adverse effect of increasing the conductor operating temperature. (a) Calculate the conductor temperature...
