If they radiate same power then (r2/r1) is A solid spherical black body of radius r and uniform mass distribution is in the free space. find the power- radiated in watt. A spherical black body of radius r radiated power `P` at temperature T when placed in surroundings at temprature `T_ (0) (lt ltT)` If `R` is the rate of colling . What is the power radiated? (ฯ = 5. If the radius is decreased A spherical black body with a radius of 12 cm radiates 450 W power at 500 K. A black body is at a temperature of `5760 K`.
