The coroner arrives at a murder scene at 9:00 pm. He immediately determines that the temperature of the body is 83◦F. He waits one hour and takes the temperature of the body again; it is 81◦F. The room temperature is 68◦F. When was the murder committed? Assume the man died with a body temperature 98◦F. (Hint: Newton’s Law of Cooling)

A coroner arrives on the scene of a homicide at 8:00 pm in a temperature-controlled room, held at 60^\circ F60 ∘ F. The temperature of the body is given by the function T(t)=27.4e^{-0.08t}+60T(t)=27.4e −0.08t +60, where tt is time in minutes since 8:00 pm. 1. Graph this function in an appropriate window and sketch below. (Please write and show the graph) 2. What happens to this function as time goes by? Why does this make sense? 3. Use the graph...

police arrive at a murder scene at 1:30 am and immediately record the body's temperature which was 93 degrees Fahrenheit. at 2:00 am, after thoroughly inspecting and fingerprinting the area, they again took the temperature of the body which had dropped to 83 degrees F. the temperature of the crime scene has remained at a constant 70 degrees F. Determine when the person was murdered. (assume that the victim was healthy at the time of death. that is, assume that...

If the temperature difference DT between an object and it surroundings is not too great, the rate of cooling or warming obeys Newton’s Law of Cooling, d(DT)/dt = – K DT where K is a constant. (a) Why is there a minus sign on the right-hand side of the equation? (b) On what factors does K depend and what are its units? (c) It DTo is the temperature difference at time to, what is the temperature difference at time t...

Murder Investigation: When a glass of wine with a certain temperature is placed into a room, its temperature will converge to the room’s temperature according to the formula: F(t)=Fs+(F0-Fs) -.3t. Where F(t) is the temperature of the object after being in the room for t hours, F0 is the initial temperature of the object, and Fs is the temperature of the room that the object is in. Use this formula to investigate the scenario below and answer the following questions....
