A spherical ***** body with a radius of 12 cm radiates 450 W power at 500 K. If the radius were halved and the temperature doubled,

Question 1

A spherical ***** body with a radius of 12 cm radiates 450 W power at 500 K. If the radius were halved and the temperature doubled, the power radiated in watts would be

(a) 225

(b) 450

(c) 900

(d) 1800

Question 2

Correct Answer is: (d) 1800

For spherical ***** body of radius r and absolute temperature T, the power radiated = (4πr2)(σT4).
