If a cup of coffee has temperature 95°C in a room where the ambient air temperature is 25°C, then, according to Newton's Law of Cooling, the temperature of the coffee after t minutes is T(t) = 25 + 70e-t/ 48 . what is the average temperature of the coffee during the first 28 minutes? average temp-C -O°C 0 If a cup of coffee has temperature 95°C in a room where the ambient air temperature is 25°C, then, according to Newton's...
7. (3 points) Suppose you are in a room with a temperature of 72 F. Newton's law of cooling states that the rate at which an object cools (or heats) is proportional to the difference between the object's temperature and the ambient temperature of the room. (a) Write down a differential equation representing Newton's Law. Let T(t) be the temperature of the object that is placed in the room (b) Solve the differential equation to find T(t). (c)Suppose T(0)-80° and...
Solve both please If a cup of coffee has temperature 96°C in a room where the ambient air temperature is 18°C, then, according to Newton's Law of Cooling, the temperature of the coffee after t minutes is T(t) 18 + 78e-t/46. What is the average temperature of the coffee during the first 20 minutes? average temp How much work is done lifting a 40 pound object from the ground to the top of a 20 foot building if the cable...
