Questions and Answers

What shape are the orbitals of planets?

  • Circles
  • Hyperbolas
  • Parabolas
  • Ellipses (correct)
  • Where are the foci and major axis located in an ellipse?

  • Foci are on the top and bottom, major axis is at the narrowest point
  • Foci are both on the left side, major axis at the widest point
  • Foci are to the left and right, major axis is through the center at the widest point (correct)
  • Foci are on the edges, major axis is at the center
  • How do you calculate eccentricity for an ellipse?

  • Eccentricity = major axis length / focal distance
  • Eccentricity = focal distance / major axis length (correct)
  • Eccentricity = focal distance / minor axis length
  • Eccentricity = minor axis length / focal distance
