Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: 746 watts
Concept:

Mechanical horsepower is a legacy unit of power that must be converted to standard SI units for physics calculations.

Formula:

$$ 1 \text{ hp} = 745.7 \text{ W} $$

Solution:

  • By standard convention in physics, this value is rounded to the nearest whole integer.


  • Therefore, 1 hp = 746 Watts.


Why other options are incorrect:

The other options are dyslexic numeral scrambles of 746 designed to confuse students relying purely on rote memorization.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
