Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Work
Concept:

The geometric area under a curve is the integral (product) of the y-axis variable and the x-axis variable.

Formula:

$$ \text{Area} = \int F dx = W $$

Solution:

  • The y-axis is Force (Newtons).


  • The x-axis is Displacement (meters).


  • Multiplying them (N \( \times \) m) yields Joules, which is the unit of Work.


Why other options are incorrect:

Area under Velocity-Time gives displacement. Power is Work divided by Time.

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.
