Question
Is the area of the uniform spherical is 4•pi•r^2?
Transcribed Image Text:a. At what temperature does a uniform spherical object of radius 15.0 cm, and surface emissivity
e = 0.9, radiate 1260 watts of total power?
b. If this same object suddenly contracts to the size of a sphere of radius 5.00 cm, but is radiating the same
total power as in part a, what will be its new temperature?
The Stefan-Boltzmann constant is o = 5.67 x 10 *W/(m²*K*).
