The spectrum of a typical star contains some hydrogen absorption lines at specific wavelengths. If these lines in the observed spectrum have wavelengths shorter than the ones measured in a laboratory on Earth, we can conclude that  … (Hint: think about the Doppler effect).

In each figure below two rocky asteroids are shown with masses (m), expressed in arbitrary units, separated by a distance (d), also expressed in arbitrary units. Three of the asteroids are identified with the letters A, B, and C. Use these figures to answer the question below. Note: the gravitational force  is F=G M  m / d2Which of the following correctly describes how the gravitational force exerted BY Asteroid A on its “partner” asteroid compares to the gravitational force exerted BY Asteroid C on its “partner” asteroid.
