Efficiency Formula
Answer: The efficiency can be found using the formula: η = 0.40 x . η = 40%. The efficiency of the hammer strike was 40%. Vibrations and heating of the nail are two possible reasons for the energy loss. 2) A particular chemical process has an energy efficiency of only 3.00%. To complete this large-scale chemical process, 140,000 J of ...
