Answer: [ML²T⁻³].
- A [ML²T⁻³]
- B [ML²T⁻²]
- C [MLT⁻²]
- D [MLT⁻³]
Correct answer: A. [ML²T⁻³]
Explanation: Power = work/time = [ML²T⁻²]/[T] = [ML²T⁻³].
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.
