Assume that the total surface area of a human body is `1.6m^(2)` and that it radiates like an ideal radiator. Calculate the amount of energy radiated per second by the body if the body temperature is `37^(@)C` . Stefan constant `sigma` is `6.0xx10^(-s)Wm^(-2)K^(-4)` .

Answer

`887 J`

Explanation

`A = 1.6m^(1) e = 1`
`(dQ)/(dt) = p sigmaeA T^(4) =(6 xx 10^(-8)) (1) 1.6 m^(2) (310)^(4)`
`= 887 J`
