A person with a normal body temperature of 36 ° C dies in an accident while traveling by car. The body temperature of this person was 30 °C when his body was found and the body temperature was 28 °C 1 hour after it was found. Also, if the temperature of the ENVERİONMENT was 20 °C when the body was found, how long before this person was found? Please express it mathematically and solve it by equation.

- The solution was indicated as wrong in my homework. Would there be another option besides statement A?One complication examining a cadaver for BAC is that the decomposition process can produce alcohol. Postmortem alcohol production is usually less than 70 mg/dL, but it can be as high as 100 mg/dL. Would it be possible to mistakenly report that a sober victim had been legally drunk at the time of death? Assume that the legal BAC level is 0.08 g/dL.left on the forest floor of the SimBody Farm for an unknown period of time. Your challenge is to estimate how long they've been dead (the postmortem age). You are given the SLOPE and INTERCEPT of the best fit line (under the graph), so you can use this information in the form of y = mx + b, where y is concentration of ammonia, x is cadaver age in hours, m is slope and b is y-intercept. To estimate body ages, substitute ammonia concentration as the y value and solve for x (age). For example, the ammonia concentration in the vitreous humor for the body at the top is 12.8 µg/mL. 112.2 hours Check Answer Q1.5. What is the postmortem age of the body located middle right? 7.9 12.8 (0.22) (age) +2.3 hours = Q1.6. What is the postmortem age of the body located at bottom left? Check Answer age = 48 hours Vitreous Ammonia (µg NH3/ml) 27.0 μg/ml 40 30- 20- 10- 0 12.8 µg/ml Slope: R²: 20 0.22 0.99 18.1 µg/ml 40 80 60 Time (Hours Post Mortem) Intercept: 2.3 0.00020 p: 100 120

AbsorbanceCan you explain how to find the answer and the calculation?The schematic below shows a human body cannulated (tubes are inserted to the body's vasculature) at three heights, B, F, and H. Blood would rise to the same height in each tube, similar to a column of water cannulated at three heights. The tubes can also be filled with a saline solution with a similar density to blood so that this will be a safer experiment to perform. For a typical adult, h, is 1.5 m and hB is 1.85 m. Using the gauge pressure at heart height from the problem above, assume the density kg of whole blood is 1060 m³ and that the average arterial (heart) pressure of this individual has been measured to be 97 mmHg. Express your answer to four significant digits. B H hB ин Image from: M. M. Sternbeim and J. W. Kane, General Physics, 2nd edition (Wiley 1991). Hint: How would you model this problem?
