Discovering the Efficiency of Scissors: A Fun Calculation!

How can we calculate the efficiency of scissors?

If you do 10 J of work while operating the scissors and the scissors do 20 J of work cutting the paper, what is the efficiency of the scissors?

Calculation of Scissor Efficiency:

The efficiency of the scissor can be calculated by determining the ratio of output work to input work. In this case, the input work done by the operator is 10 J while the output work done by the scissors is 20 J.

To calculate efficiency:

Efficiency = (Output/Input) x 100%

Given that the output work is 20 J and the input work is 10 J:

Efficiency = (20/10) x 100%

Efficiency = 2 x 100%

Efficiency = 200%

Therefore, the efficiency of the scissors in this scenario is 200%. This means that the scissors are quite effective in converting input work into output work while cutting the paper.
