a) using the values of resistance for arm (400 ohm), leg (200), andtrunk(50), calculate the power dissipated in the arm, leg, andtrunk.
b) the specific heat of water is 4.18x10^3 J/kg(deg)C, so a mass ofwater M (in kilograms) heated by a power P (watts) undergoes a risein temp. at a rate given by:
dT/dt = (2.39x10^-4 P)/(M) degrees C/s
assuming that the mass of an arm is 4kg, the mass of a leg is 10kg,trunk 25kg, and that the human body is mostly water, how many seconds does it take the arm, leg, trunk to rise the 5 deg. C that endangers living tissue?
c) how do the values you computed in b compare with the few minutesit takes for oxygen starvation to injure the brain?
