Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Power Watt
Concept:

Standardization of the International System of Units (SI).

Solution:

  • Power measures the rate of doing work (Joules per second). The SI derived unit for this is the Watt (W).


Why other options are incorrect:

Energy is Joules. Force is Newtons. Velocity is \( \text{m/s} \) (\( \text{m/s}^2 \) is acceleration).
