With an energy input of 300 J and an efficiency of 15%, the machine produces 45 J of useable energy.
<h3>
What is energy?</h3>
Energy is characterized as a quantitative characteristic that is transmitted to a person or a physical system and can be observed in the manner in which labor is accomplished as well as in the generation of heat and light. The sun is one of the most significant energy sources.
The machine's useful energy output, or work output, can be calculated as follows:
Efficiency = work out / work in x 100
0.15 = work out / 300
Multiply by cross
Production = 0.15 x 300
Production: 45 J
Thus, with an energy input of 300 J and an efficiency of 15%, the machine produces 45 J of useable energy.
