Over a period of time, a hot object cools to the temperature of the surrounding air. this is described mathematically as newtons law of cooing t=c+(t_0-c)e^-kt, where t is the time it takes for an object to cool from the temp t_0 to the temp t, c is the surrounding air temp, and k is a positive constant tat is associated with the cooling object. a cakes removed from the oven has a temp of 207 degrees f and is left to cool in a room that has a temp of 69 degrees f. after 20 min the temp of the cake is 138 degrees f. what is the temp of the cake after 35 min?

110.03 °F is the temp of the cake after 35 minutes.

Explanation:

Newtons Law of Cooing is given by:

t = Time it taken by an object to cool from the temp to the temp T

C = temperature of the surrounding

k =  Constant that is associated with the cooling object

We will first calculate the value of k.

Substituting the values in a given formula:

The temperature of the cake after 35 min:

T = 110.03 °F

110.03 °F is the temp of the cake after 35 minutes.

colorectal cancer may also develop from areas of abnormal cells in the lining of the colon or rectum. this area of abnormal cells is called dysplasia and is more commonly seen in people with certain inflammatory diseases of the bowel such as crohn's disease or ulcerative colitis.
