Ahypthetical new mineral: unobtanium. unobtanium, when pure, is transparent and is very refractive. when the incident light ray strikes the surface at 45 degrees (sin 45 = 0.71), the refractive measures 12 degrees (sin 12 = 0.21)(all angles are measured from the normal). what is the refractive index of unobtanium?

Acar moves a distance of 50.0 km west, followed by a distance of 64.9 km north what was the magnitude of the displacement of the car, in units of kilometers?

However, had it been a real sound, the sound's pitch would have been increased by the doppler effect, since the falcon was moving the source of the sound. perpendicular to away from towards at the same speed as

Identify the correct relation showing that the radius r of the orbit of a moon of a given planet can be determined from the radius r of the planet, the acceleration of gravity at the surface of the planet, and the time τ required by the moon to complete one full revolution about the planet. determine the acceleration of gravity at the surface of the planet jupiter knowing that r = 71 492 km and that t= 3.551 days and r= 670.9 × 10^3 km for its moon europa.
