Answer: [ML²T⁻²].
- A [ML²T⁻²]
- B [MLT⁻²]
- C [ML²T⁻³]
- D [MLT⁻¹]
Correct answer: A. [ML²T⁻²]
Explanation: Work = force × distance = [MLT⁻²][L] = [ML²T⁻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.
Concept context
SI base units, dimensional analysis, significant figures, and error propagation. The toolkit every physics calculation relies on.
