Find the efficiency of a machine that does 800 J of work if the input work is 2,400 J.
Question
Solution 1
To find the efficiency of a machine, we can use the formula:
Efficiency = (Output work / Input work) * 100%
Given that the machine does 800 J of work (output work) and the input work is 2,400 J, we can substitute these values into the formula:
Efficiency = (800 J / 2,400 J) * 100%
