\begin{gathered} F_(input)=20N \\ F_(output)=100N \\ MA=? \\ MA=(F_(output))/(F_(input))=(100N)/(20N)=5 \\ MA=5 \\ The\text{ mechanical advantage is 5} \\ \\ Question\text{ 2\rparen} \\ W_(input)=380J \\ W_(output)=500J \\ \eta=? \\ \eta=(W_(output))/(W_(input))=(500J)/(380J)=1.316=131.6 \\ The\text{ efficiency is 131.6\%} \end{gathered}
