- Q12Which of the following is a significant piece of evidence that supports the Nebular Hypothesis?Scientists can use telescopes to observe solar systems forming throughout the universe.The characteristics of the planets support that they formed at the same time as the sunThe sun's composition suggests that it formed after the planetsAll of our planets orbit in various patterns45s
- Q13According to Kepler's First law, the pattern that the the planets orbit in is due to...the solar system having 2 foci instead of 1the solar system's compositionthe solar system's location in the galaxythe solar system having 1 foci instead of 245s
