if your actual mechanical advantage is 10 j and the theoretical is 40 j, wjat is your percent efficiency? hint: % efficiency = (actual MA/Ideal MA) * 100

A)0.25%
B)400%
C)25%
D)4%

The percent efficiency can be calculated by using the following formula:

% efficiency = (actual MA / ideal MA) * 100

Plugging in the given values:

% efficiency = (10 J / 40 J) * 100

Simplifying:

% efficiency = (1/4) * 100 = 25%

Therefore, the correct answer is C) 25%.
