Physics And Measurement Question 269

Question: The unit of the Stefan-Boltzmann’s constant is

Options:

A) $W / m^{2} k^{4}$

B) $W / m^{2}$

C) $W / m^{2} K$

D) $W / m^{2} K^{2}$

Show Answer

Answer:

Correct Answer: A

Solution:

[a] $E = σ A T^{4}$ E is energy dissipated per second. $σ = \frac{E}{A T^{4}} = \frac{W a t t}{m^{2} K^{4}}$
