Answer: Luminous intensity.
- A Luminous intensity
- B Velocity in standard reference material
- C Force under most conditions studied
- D Momentum in most observed cases
Correct answer: A. Luminous intensity
Explanation: Luminous intensity (candela) is one of the seven SI base quantities, while velocity, force, and momentum are all derived quantities.
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.
