6. Newton's law of cooling states that the temperature of an object changes at a rate proportional e difference between the temperature of the object and the temperature of its surroundings. to (a) Multiple Choice: The temperature of a cup of coffee obeys Newton's law of cooling. The initial temperature of the coffee is 150°F and, one minute later, it is 135°F. The ambient temperature of the room is 70° F. If H(t) represents the temperature of the coffee at time t, and k is a positive constant, the correct differential equation that models this situation is: (Select the correct answer). dH i. =k(T-135) dt dH
