a. Spica (a star in the constellation Virgo with a surface temperature of 18,000K).






b. The Earth (with an average surface temperature of 59°F)






c. A human body (with an average temperature of 98.6°F)







d. Pluto (a dwarf planet with an average temperature of 44K

The Formula is P = s*T^4 where s= Stefan-Boltzman constant = 5.67x10^-8 W/m^2-K and T = surface temperature in Kelvin
Please Help I have no clue what to do.
