4. Newton's Law of Cooling states that the rate of cooling of an object is proportional tothe temperature difference between the object and its surroundings. A roast turkey istaken from the oven when tis temperature has reached 185 F and is placed on a table ina room where the temperature is 75 F.a) If the temperature of the turkey is 150 F after half an hour, what is the temperatureafter 45 minutes?b) When will the turkey have cooled to 100F?c) Find a formula for the temperature of the turkey at time t.d) Plot the formula from (c).

As per BARTLEBY rules i answer only first 3 parts ,so i hope you understand.

Q5) Method of Joints The structure on the right is in static equilibrium. It is constructed using two-force members, joined at their ends. I have given you all the external forces acting on the structure. You do not need to find reaction (support) forces. a) Label every member as tension T, compression C, or zero-force Z. Draw arrows on every non-zero member to indicate the direction of the tension or compression forces. b) Use the Method of Joints to calculate the magnitude of forces F1 , F2 , and F3. Follow the recipe and show all your work. Clearly draw free-body-diagrams and write Newton’s 2nd law for every joint you study.
