A) Work, energy, force
B) Velocity, momentum, impulse
C) Potential energy, kinetic energy, momentum
D) Pressure, stress, coefficient of elasticity
Correct Answer: D
Solution :
\[Pressure=Force=\frac{[ML{{T}^{-2}}]}{[{{L}^{2}}]}=[M{{L}^{-1}}{{T}^{-2}}]\] \[Stress=\frac{Force}{Area}=\frac{[ML{{T}^{-2}}]}{[{{L}^{2}}]}=[M{{L}^{-1}}{{T}^{-2}}]\] Coefficient of elasticity \[=\frac{Stress}{Strain}\] \[=\frac{F/A}{L/L}=\frac{[ML{{T}^{-2}}][{{L}^{-2}}]}{[L]/[L]}\] \[=[M{{L}^{-1}}{{T}^{-2}}]\]
