The correct unit of energy density is?
A
kg m3 s-2
B
kg m2 s-2
C
kg m-3 s-2
D
kg m-1 s-2
Verified Correct Answer: D.
Physical Principles & Numerical Solution
Energy density = \(\frac{\text{Energy}}{\text{Volume}}\) = \(\frac{\text{Joule}}{m^3}\) = \(\frac{kg m^2 s^{-2}}{m^3}\) = kgm\(^{-1}\)s\(^{-2}\)
