Match the physical quantities with their correct $\mathrm{SI}$ units.

The correct match is

If momentum $\left(P\right),$ area $\left(A\right)$ and time $\left(T\right)$ are taken to be the fundamental quantities then the dimensional formula for power is:

Which of the following equation is dimensionally inconsistent? Here, $\left[l\right]=\left[l_0\right]=L$, and $\left[m\right]=\left[m_0\right]=M$. 

The displacement of an oscillating particle is $y=E \sin \left(Fx+Gt+H\right).$ The dimension of quantity $X=EFGH$ in terms of mass $\left(M\right),$ length $\left(L\right)$ and time $\left(T\right)$ is
