If you grease a ramp to make a box slide more easily, what happens to the ramp mechanical advantage? explain your answer.

Answer is: the ramp's mechanical advantage increases because friction has been reduced.
Friction is the force resisting the relative motion.
Lubrication is the process that reduce friction between surfaces in moving to each other.
Grease is a liquid-liquid dispersion that possess a high viscosity and allows smooth continuous operation of equipment.

No because a circle or pie graph usually shows percentages you'd need a line graph
