Answer: [L²T⁻²].
- A [L²T⁻²]
- B [LT⁻¹]
- C [LT⁻²]
- D [L²T⁻¹]
Correct answer: A. [L²T⁻²]
Explanation: as = [LT⁻²][L] = [L²T⁻²], matching v² as required by homogeneity.
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.
