Question

. An internal combustion engine has an efficiency of 20.0%. This engine is

used to deliver 6.00 × 104 J of work to the rest of the drive train. What is
total energy input of the engine?

Answer 1

The total energy input of the engine can be calculated by using the formula:

Energy Input = Energy Output / Efficiency

Therefore, in this case:
Energy Input = 6.00 × 104 J / 0.20 = 3.00 × 105 J

The total energy input of the engine is 3.00 × 105 J.
