Question

If input energyis 100J and useful is 70J what is the waste energy

Answer 1

waste energy = 30 J

Step-by-step explanation:

Given that.

Input energy = 100 J

Useful energy = 70 J

We need to find the amount of waste energy.

Waste energy = total energy - used energy

= 100 J - 70 J

= 30 J

Hence, 30 J of energy is waste energy.
