Answer 1

Your answer is C.12.0 Hope this helps.

Answer 2

Answer: MA = 12.0

Explanation: The mechanical advantage is deffined as the "amplification" of the force done by a tool.

If the imput force is 50N, and the output force is 600N, the mechanical advantage can be calculated as:

MA = Fo/Fi

where Fo is the output force and Fi is the imput force.

MA = 600N/50N = 12.0

Then the mechanical advantage of the axe is 12.0
