Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: 10 watt
Concept:

Power is defined as the rate at which work is done or energy is transferred.

Formula:

$$ P = \frac{W}{t} $$

Solution:

  • Given Work (\( W \)) = 100 J


  • Given Time (\( t \)) = 10 s


  • Substitute the values: \( P = \frac{100}{10} = 10 \text{ W} \)


Why other options are incorrect:

Multiplying work and time gives 1000 W (Option A). Confusing the values or incorrectly placing the decimal gives 100 W or 0.10 W.
