Explanation:

A student working in a grocery store after school pushes several grocery carts together along a ramp. The ramp is 3 meters long and rises 0.5 meter. What is the ideal mechanical advantage of the ramp?

The ramp is an example of a simple machine

definition of terms

a machine is a device which enables work to be done in a quick and convenient way

mechanical advantage is work input/work output. also the ratio of load to effort

for the question given we simply say

work input/ work output

3/0.5=

6,

mechanical advantage is basically unitless.

snell's law

refractve index = sin incidence / sin refraction
