Answer: [M L T⁻²].
- A [M L T⁻¹]
- B [M L T⁻²]
- C [M L² T⁻²]
- D [M L⁻¹ T⁻²]
Correct answer: B. [M L T⁻²]
Explanation: Force = mass × acceleration = [M][L T⁻²] = [M L T⁻²].
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.
