Most Missed Space (old)

An astronomer was comparing the composition of two different stars. She found that the stars are about the same size. She also found that the percentage of hydrogen in one star was much less than in the other. 

 What can she best conclude from this observation?

• The star with the most hydrogen was older.

•  The star with the most hydrogen had less mass.

• The star with the most hydrogen was younger.

• The star with the most hydrogen was less bright

 What is the best argument that can be made from this data?

•  More distant galaxies are moving away faster.

• More distant galaxies are moving toward us faste

• More distant galaxies are brighter.

• More distant galaxies are not as bright.

Which of the statements below best describes the motion of Earth's Moon during one revolution?
