Question
Find the dimensions of:
  1. Linear momentum.
  2. Frequency.
  3. Pressure.

Answer

  1. Linear momentum: $\text{mv}=[\text{MLT}^{-1}]$

  2. Frequency: $\frac{1}{\text{T}}=[\text{M}^0\text{L}^0\text{T}^{-1}]$

  3. Pressure: $\frac{\text{Force}}{\text{Area}}=\frac{[\text{MLT}^{-2}]}{\text{[L}^2]}=[\text{ML}^{-1}\text{T}^{-2}]$
