Question

Question 2 (1 point) A cubic structure of side length 1.00 m is at a temperature of 293 K and is located in an environment that is at a temperature of 273 K. If the cube surfaces have an emissivity of 1.00 and emit radiant energy equally from all sides, what is the net power radiated? A) 155 W O B) 323 W O C) 618 w 。D)1290 w O E) 450 W Save Page 2 of 10

Answer 1

The 'Surface avea of Cube is e = 6x1 6m. So , the Power vadiahan is oiven we have Th=243 k , =273 k. So p = 1(5.6703 XI -8)(6) ($43.773 | p= 617.66 W 618
