How do you solve this Differential Equation question using Newton's Cooling Law? Please explain carefully; the answer is 72 minutes. A cake is removed from an oven at 196 degrees F and left to cool at room temperature, which is 60 degrees F. After 35 minutes, the temperature of the cake is 115 degrees F. When will the cake be 81 degrees F?

Newton's Law of Cooling states that the rate of cooling of an object is proportional temperature difference between the object and its surToundings. Suppose that a roast turkey is taken from an oven when its temperature has reached 160°F and is placed on a table in a room where the temperature is 60°F. If zu) is the temperature of the turkey after t minutes, then Newton's Law of Cooling implies that to the 7 du k(u-60) dt This could be...

According to Newton's law of cooling, the time t needed for an object at an initial temperature To to cool to a temperature T in an environment with ambient temperature T, is given by In(7,-%) In(T-Ta) where k is a constant. Assume that for a certain type of container, k = 0.025 min.. Let t be the number of minutes needed to cool the container to a temperature of 50F. Assume that To = 70.1 ± 0.2·F and Ta =...

8) If an object is heated and then exposed to the air, it will lose heat at a rate which is proportional to the instantaneous difference in temperature between the object and the air. The decay of the object temperature back to the air temperature is given by: T=Toe^(-t/T) Where To is the initial temperature elevation of the object and T is the elevation of the object temperature at later times. The symbol “t” is the time after the heated...
