According to the Stefan-Boltzmann law, the radiative energy emitted by one square meter of an object is equal to a constant multiplied by its temperature raised to the _______ power.

The correct answer is C. Fourth.

The Stefan-Boltzmann law states that the total energy radiated per unit surface area of a blackbody in unit time is proportional to the fourth power of the blackbody’s thermodynamic temperature, T.

The Stefan-Boltzmann constant, σ, is a physical constant that is used in the Stefan–Boltzmann law to calculate the amount of energy radiated by a blackbody. It is a dimensionless constant with a value of 5.670373 × 10−8 W/m2/K4.

The Stefan-Boltzmann law can be written as:

E = σT4

where:

E is the energy radiated per unit surface area in unit time

σ is the Stefan-Boltzmann constant

T is the thermodynamic temperature of the blackbody

The Stefan-Boltzmann law is a fundamental law of physics that is used to calculate the amount of energy radiated by a blackbody. It is a very important law in astrophysics and is used to calculate the luminosity of stars and other astronomical objects.
