Answer 1

Answer:

2

Explanation:

Mechanical advantage is ratio of load lifted to effort applied to it.  

 

M. A. space equals space fraction numerator L o a d over denominator E f f o r t end fraction

O R

M. A equals space fraction numerator E f f o r t space a r m over denominator L o a d space a r m space end fraction

 

Here, effort arm (handles of scissor) = 10 cm  

and load arm (blades of scissor) = 2 cm

 

M. A space equals space fraction numerator space 10 space c m over denominator 5 space c m space end fraction equals space 2

Thus, mechanical advantage of the scissor = 2
