Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Work
Concept:

On a graph, the area under the curve is the product of the quantities on the y-axis and x-axis.

Formula:

$$ W = \int F dx $$

Solution:

  • The y-axis represents Force (F).


  • The x-axis represents Displacement (d).


  • Area = F \( \times \) d, which is the definition of Work Done.


Why other options are incorrect:

Area under Velocity-Time gives displacement. Power is work divided by time, not force times displacement. Acceleration is force divided by mass.

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.
