In a simple the energy input is 120j if the efficiency of the machine is 80% calculate the energy output
In a simple what?
% efficiency = (output/input)*100
80 = (output/120)*100
Solve for output.
To calculate the energy output, we can use the formula:
Energy output = Energy input x Efficiency
Given:
Energy input = 120 J
Efficiency = 80% = 0.8 (since, efficiency is expressed as a decimal)
Substituting the values into the formula, we get:
Energy output = 120 J x 0.8
Energy output = 96 J
Therefore, the energy output is 96 J.
