Newton's law of cooling is , where is the temperature of an object, is in hours, is a constant ambient temperature, and is a positive constant. Suppose a building loses heat in accordance with Newton's law of cooling. Suppose that the rate constant has the value Assume that the interior temperature is , when the heating system fails. If the external temperature is , how long will it take for the interior temperature to fall to

Complete Question

The complete question is shown on the first uploaded image

The time taken  is  

Explanation:

From the question we are told that

       The value of  

       The  the interior temperature is  

         The external temperature is  

          The required interior temperature is  

      The newton cooling law is

=>                

  Now integrate both sides we have  

Since c is a constant lnC = c   will also give a constant so

       =>      

     =>          

          substituting value

Hence

=>    

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated

don't remove my answer im trying my best to answer them

explanation:

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
