The Stefan - Bolizmann law is expressed in the form. __ BblbepuTe oAMH OTBer: R=sigma T^4 S=kcdot lnW E=hv

The correct answer is **R = σT⁴**.The Stefan-Boltzmann Law describes the power radiated from a black body in terms of its temperature. It states that the total energy radiated per unit surface area of a black body across all wavelengths per unit time is directly proportional to the fourth power of the black body's thermodynamic temperature.Where:* **R** represents the radiant heat energy emitted per unit time per unit area.* **σ** is the Stefan-Boltzmann constant (approximately 5.67 x 10⁻⁸ W⋅m⁻²⋅K⁻⁴).* **T** is the absolute temperature of the black body in Kelvin.The other options represent different physics concepts:* **S = k⋅lnW** is Boltzmann's entropy formula, relating entropy (S) to the number of microstates (W) of a system.* **E = hv** is Planck's equation, relating the energy (E) of a photon to its frequency (v).
