A5-meter ramp lifts objects to a height of 0.75 meters. what is the mechanical advantage of the ramp?

This is an Engineering question, and the answer is reasonably simple. The mechanical advantage is given by:

MA =  on a lever or ramp system.

MA = 

MA = 6.67 (there are no units, as MA is a ratio)

Are there any options that could alot..

Atp, shorthand for adenosine triphosphate, is the standard molecule for cellular enger in the human body. all motion and metabolic  processes  within the body begins with energy that is released from  atp, as its phosphate bonds are broken in cells through a  process  called hydrolysis.
