# Match the following:

 Energy $ML^{-1}T^{-2}$ Torque $ML^2T^{-2}$ Planks Constant $ML^2T^{-1}$ Angular Momentum $MLT^{-1}$

1,5,10,14

##### SOLUTION
Energy E = Work done = $Force \times displacement$
or $E=\left[MLT^{-2}\right]\left[L\right]=\left[ML^{2}T^{-2}\right]$.

Torque, $\tau =Force \times$ perpendicular distance
Or, $\tau=\left[MLT^{-2}\right]\left[L\right]=\left[ML^{2}T^{-2}\right]$.

Planck's Constant $h=\dfrac { E }{ \nu } =\dfrac { ML^{ 2 }T^{ -2 } }{ { T }^{ -1 } } =ML^{ 2 }T^{ -1 }$

Angular Momentum $\vec { L } =\vec { r } \times \vec { P } =\left[ L \right] \left[ M \right] \left[ LT^{ -1 } \right] =\left[ ML^{ 2 }T^{ -1 } \right]$
