1.       What is the Newton’s Law of Cooling?
It is a formula(y-y1=Cekt) used to know the temperture of objects or bodies in a certain period of time. It could be used to determinate the time of death of a person. 
2. What variables in your problem correspond with the variables in the Newton’s Law of Cooling?
 in our problem we are looking for the time of death, so we have the "y", "y1", "c", we have to find "k" in order to get "t" 
3. According to this Law, at what time approximately the death happened? Like 3 hours ago we found the body. And we find the body at 3:00 PM. so we conclude the teacher was killed at 12:00 pm.
4. How does the room temperature affect the time of death?
It affects a lot, because the objects always wants to reach the temperature of the enviroment. So it is an essential factor in our project.
5. How does an illness (e.g. fever) affect the time of death?
It affects becase we dont know what was the exact temperture of the body, so we cannot use the Newton’s Law of Cooling. 
6. How exact is the approximation of the Newton’s Law of Cooling for predicting the time of death? it could be exact if we know exactly what is the initial temperture of the body(when it eas alive), but if the body is removed for one place to other, it doesn't work anymore.
