- A [MLT⁻¹]
- B [MLT⁻²]
- C [ML²T⁻¹]
- D [ML²T⁻²]
Correct answer: A. [MLT⁻¹]
Explanation: Momentum = mass × velocity = [M][LT⁻¹] = [MLT⁻¹].
The 7 SI base units. All derived units (newton, joule, watt, volt, etc.) can be expressed as combinations of these 7 fundamental units raised to various powers.
