OFFERING 30 POINTS!!

Refer to Figure 7-2(d). If a force of 200 N is required to lift a 50 kg load, find the IMA, AMA, and efficiency for the system.
(Fw = 100 N)

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.
