Options

  1. Aa-p b-r c-s d-q
  2. Ba-p b-s c-r d-q
  3. Ca-q b-r c-s d-p
  4. Da-s b-s c-r d-s

Correct answer

D. a-s b-s c-r d-s

Step-by-step solution

Final Dimensions: The SI unit of Stefan's constant is W m (\mathrmm^{-2}  K−4\mathrm{~K}^{-4} (\left[M^1 L⁰ T^{-3} K^{-4}\right]) Wein's constant = Wavelength (×\times temperature= [L (θ\theta] Emission power= Power/ Area- W/m^2 (SI unit) (=[MT−3]\left[\mathrm{MT}^{-3}\right] Thermal resistance= Dimensional Formula: [R]=M−1L−2T3K1[R]=M^{-1} L^{-2} T³ K¹
