Question
Find the dimensions of:
- Linear momentum.
- Frequency.
- Pressure.
✓
Answer
- Linear momentum: $\text{mv}=[\text{MLT}^{-1}]$
- Frequency: $\frac{1}{\text{T}}=[\text{M}^0\text{L}^0\text{T}^{-1}]$
- Pressure: $\frac{\text{Force}}{\text{Area}}=\frac{[\text{MLT}^{-2}]}{\text{[L}^2]}=[\text{ML}^{-1}\text{T}^{-2}]$
