    \[[M{{L}^{2}}{{T}^{-3}}]\] represents the dimensions of:

    A)  pressure            

    B)  energy

    C)  power                                 

    D)   force

    Correct Answer: C

    Solution :

    Power\[\frac{work}{time}=\frac{F\times d}{t}=\frac{ma\times d}{t}\] Dimensions of power \[=\frac{\text{dimensions}\,\,\text{of}\,\,ma\times \text{dimensions}\,\,\text{of}\,\,d}{\text{dimensions}\,\,\text{of}\,\,t}\] Dimensions of power\[=\frac{[ML{{T}^{-2}}]}{[T]}=[M{{L}^{2}}{{T}^{-3}}]\]
