Is it possible for the Efficiency to be greater than 100%? Why or why not?

No, it is not possible for efficiency to be greater than 100%. Efficiency is a measure of how well resources are used to accomplish a task or goal, and it is calculated by dividing the actual output by the expected or possible output and then multiplying by 100 to get a percentage.

If the actual output is greater than the expected or possible output, the efficiency may appear to be greater than 100% when calculated. However, this is not accurate as efficiency is meant to show the relationship between resources used and the outcome achieved. An efficiency greater than 100% would suggest that more output was achieved than was theoretically possible, which is not possible in practical terms.

In summary, efficiency greater than 100% is not possible because it would imply that more output was achieved than was theoretically possible, which defies the laws of physics and practicality.
