A76 -ton monolith is transported on a causeway that is 2500 feet long and has a slope of about 3.4 degrees. how much force parallel to the incline would be required to hold the monolith on this causeway?

What would occur if the index of refraction of a material was less than n=1? the speed of light would increase to a speed larger than the maximum speed of light in a vacuum. the light wave would not bend at all though the material. the light wave would not be able to refract and would instead reflect off of the material. the speed of light would reduce to values close to 0 m/s.
