A human body has a surface area of approximately 1m^2. The normal body temperature is 10K above the surrounding room temperature T0. Take the room temperature to be T0=300K. For T0=300K (sigma)(T0)^4=460W/m^2. Which of the following options are/are correct?
A) The amount of energy radiated by the body in 1s is close to 60J.
B) If the room temperature reduces by (delta)T0, in order for the human (living) temperature to remain constant, the human needs to radiate (delta)W=4(sigma)(T0)^3(deltaT0) more per unit time.
C) reducing the exposed surface (by curling up) allows the person to maintain temperature while reducing energy loss,
D) If the body temperature rises significantly then the peak of the spectrum of E&M emitted by the body will shift to the longer wavelengths.
