You are evaluating the feasibility of a device that will monitor the breathing of patients in a hospital. The device is an elastic band, containing many loops of a conductive material, that goes around a patient’s torso. As the patient breathes, the size of the band changes. You decide to calculate the number of loops necessary to generate a detectable emf in the band (which must be at least 1 mV). You know that the average value of the Earth’s...

1. Solve the given initial value problem. dy/dt = (t^3 + t)/(y^2); y(0) = 2 . 2. We know from Newton’s Law of Cooling that the rate at which a cold soda warms up is proportional to the difference between the ambient temperature of the room and the temperature of the drink. The differential equation corresponding to this situation is given by y' = k(M − y) where k is a positive constant. The solution to this equation is given...

A patient who has asthma is given a continuous infusion of theophylline to relax and open the air passages in his lungs. The desired steady-state level of theophylline in the patient’s bloodstream is 15 mg/L. The average half-life of theophylline is about four hours, and the patient has 5.6 L of blood in his body. This situation can be modeled by the differential equation dy/dt=a-by, where y left-parenthesis t right-parenthesis is the amount of theophylline in the blood plasma at...
