Police arrive at a murder scene at 2:30 AM and immediately record the body's temperature which was 91°F. At 3:00 AM, after thoroughly inspecting and fingerprinting the area, they again took the temperature of the body which had dropped to 86°F. The temperature of the crime scene has remained at a constant 71°F. Determine when the person was murdered. (Assume that the victim was healthy at the time of death. That is, assume that the temperature of the body at...

Police arrive at a murder scene at 2:30 AM and immediately record the body's temperature which was 93°F. At 3:30 AM, after thoroughly inspecting and fingerprinting the area, they again took the temperature of the body which had dropped to 84°F. The temperature of the crime scene has remained at a constant 80°F. Determine when the person was murdered. (Assume that the victim was healthy at the time of death. That is, assume that the temperature of the body at...

Question 2 You are working as a crime scene investigator and must predict the temperature of a homicide victim over a 5-hr period. You know that the room where the victim was found was at 10 "C when the body was discovered. Newton's law of cooling says that the temperature of a body changes at a rate proportional to the difference between its temperature and that of the surrounding medium (the ambient temperature), where T = the temperature of the...

The body starts at 98.6 degrees and cools from there.
Application of Newton's Law of Cooling dT/dt = -K (T-Tm ) for k> 0 Question: Determination of the time of death (Homicide, or accidental death ) If the discovered body measured as 850 F, and checked as 740 Ftwo hours later. Also, the constant temperature of the medium around the body Tm = 68°F. Step 1: set up the system Step 2: solve the system Answer: The body was discovered...

1. A detective is called to a crime scene in an apartment. She arrives at noon and finds the thermostat set to 72 degrees F. She also finds a body, which is at 78 degrees F. She examines the area for clues, and then rechecks the body's temperature at 1:00 PM, and finds it to be 75 degrees F. Given that normal (living) body temperature is 98.6 degrees F, at what time did the murder occur? 2. A snowball melts...

M 6. The equation for logistic growth has the general form y = 1+ Be-M -M , where M, B, and k are positive constants and M represents the maximum level that y can obtain. Suppose that a lake is stocked with 100 fish. After 3 months there are 250 fish. A study of the ecology of the lake predicts that the lake can support 1000 fish. Find a logistic function for the number NO) of fish in the lake...
