Newton's law of cooling states that the temperature of an object changes at a rate proportional to the difference between its temperature and that of its surroundings. If we measure temperature in degrees Celsius and time in minutes, the constant of proportionality k equals 0.2. Suppose the ambient temperature TA(t) is equal to a constant 83 degrees Celsius. Write the differential equation that describes the time evolution of the temperature T of the object.
