    An asteroid is in an elliptical orbit around the sun. The perihelion is 316.191

    Gm and the length of the minor? axis is 836.492 Gm. Find an equation of an ellipse that could model the orbit of this asteroid. Assume the center is located at the origin.

    A beam of light enters the flat surface of a diamond at an angle of 30 degrees from

    the normal. The angle of? refraction in the diamond is measured to be 12 degrees from the normal.(sin 30 degrees = 0.50, sin 12 degrees = 0.21) Determine the index of refraction for the diamond. How would i figure this out?

    An electric drill rated at 400 W is connected to a 120 V power line. What is the...

    ...resistance of the drill? Do i just divide 400W by 120V?
