A tube with a cylindrical shape rolls down a slope inclined at angle $\theta$ and travels a distance $L$ in a time $T$. The quantities are linked by $L\left(3 + \frac{a^2}{P}\right) = QT^2 \sin \theta$, where $a$ denotes the internal radius of the tube and $P$ and $Q$ are constants. Which row shows the correct units of $P$ and of $Q$?
