Assuming that the human skin has a 1.0cm thick layer of skin tissue and a surface area of 1.5m^2, estimate the rate at which heat is conducted from inside the body to the surface if the skin temp. is 34'C (Assume a normal body temp. reads 37'C for the temp of the interior.
If you are in an automobile accident with an initial speed of 107km/h and are stopped by an airbag that inflates from the dashboard,over what distance must the airbag stop you for you to survive thecrash?The human body can survive a negative acceleration trauma incident(sudden stop) if the magnitude of the acceleration is less than 250m/s^2
The human body converts internal chemical energy into work andheatat rates of 60 to 125 W (called the basal metabolicrate).This energy comes from food and is usually measured inkilocalories[1 kcal = 4.186 kJ]. (Note that thenutritional `Calorie'listed on packaged food actually equals 1kilocalorie). How manykilocalories of food energy does a personwith a metoblic rate of105.0 W require per day? (Assume100 percent efficiency.)
