Compared to our solar system, the universe is

• younger, smaller, and contains fewer stars
• younger, larger, and contains more stars
• older, smaller, and contains fewer stars
• older, larger, and contains more stars

The diagram below represents the spectral lines from the light emitted from a mixture of two gaseous elements in a laboratory on Earth. If the same two elements were detected in a distant star that was moving away from Earth, how would the spectral lines appear?

• The entire set of spectral lines would shift toward the red end
• The entire set of spectral lines would shift toward the blue end.
• The spectral lines of the shorter wavelengths would move closer together.
• The spectral lines of the longer wavelengths would move closer together.

The gravitational attraction between two objects in the solar system is greatest when their masses are

The diagrams below represent spectral lines of hydrogen gas observed in a laboratory and the spectral lines of hydrogen gas observed in the light from a distant star. Compared to the spectral lines observed in the laboratory, the spectral lines observed in the light from the distant star have shifted toward the

• red end of the spectrum, indicating the star’s movement toward Earth
• red end of the spectrum, indicating the star’s movement away from Earth
• blue end of the spectrum, indicating the star’s movement toward Earth
• blue end of the spectrum, indicating the star’s movement away from Earth
