a treadmill takes 600 j total, but it only uses 480 j to function. what is the efficiency of the treadmill? ? % hint : efficiency = usable e / total e · 100
Answer
Explanation:
Step1: Identify values
Usable energy $E_{usable}=480\ J$, total energy $E_{total}=600\ J$.
Step2: Apply efficiency formula
Efficiency $\eta=\frac{E_{usable}}{E_{total}}\times100=\frac{480}{600}\times100$.
Step3: Calculate result
$\frac{480}{600}\times100 = 80$.
Answer:
80
