Answer: [LT⁻¹].
- A [LT⁻¹]
- B [LT⁻²]
- C [L²T⁻¹]
- D [MLT⁻¹]
Correct answer: A. [LT⁻¹]
Explanation: Velocity = displacement/time = [L]/[T] = [LT⁻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.
Concept context
SI base units, dimensional analysis, significant figures, and error propagation. The toolkit every physics calculation relies on.
