A thick layer of oil floats on top of some water in a cup. If a light ray hits the boundary between the oil and water at an incident angle of 31.0 deg., and refracts into the water at an angle of 34.4 deg., what is the index of refraction of the oil, n_1?
a: n_1 = 1.46
b: n_1 = 0.751
c: n_1 = 1.10
d: n_1 = 1.21

After the near spacecraft passed mathilde, on several occasions rocket propellant was expelled to adjust the spacecraft's momentum in order to follow a path that would approach the asteroid eros, the final destination for the mission. after getting close to eros, further small adjustments made the momentum just right to give a circular orbit of radius 45 km (45 × 10^3 m) around the asteroid. so much propellant had been used that the final mass of the spacecraft while in circular orbit around eros was only 545 kg. the spacecraft took 1.04 days to make one complete circular orbit around eros. calculate what the mass of eros must be.
