3. 9 th Grade Science #1. Based on Student 2’s discussion, Algol B is part of the present Algol system because of which of the following forces exerted on Algol B by the original Algol system? A.Electric force B.Magnetic force C.Gravitational force D.Nuclear force

4. 9 th Grade Science #2. Based on Student 1’s discussion and Fact 4, while matter flowed between Algol A and Algol B, Algol B produced the majority of its energy by fusing: A.hydrogen nuclei to make helium nuclei at its center. B.hydrogen nuclei to make helium nuclei in a shell surrounding its center. C.helium nuclei to make hydrogen nuclei at its center. D.helium nuclei to make hydrogen nuclei in a shell surrounding its center.

5. 9 th Grade Science #3. Suppose that chemical composition is uniform among stars formed from the same cloud of gas and dust, but that chemical composition varies among stars formed from different clouds of gas and dust. Student 2 would most likely agree with which of the following statements comparing the chemical compositions of the stars in the present-day Algol system at the time they formed? A.Algol A and Algol B had the most similar compositions. B.Algol A and Algol C had the most similar compositions. C.Algol B and Algol C had the most similar compositions. D.Algol A, Algol B, and Algol C had the same composition.

6. 9 th Grade Science #4. If the mass of the Sun is 2.0 x 10 30 kg, what is the mass of Algol C? A.1.6 x 10 30 kg B.2.0 x 10 30 kg C.3.4 x 10 30 kg D.7.2 x 10 30 kg

7. 9 th Grade Science #5. Which of the following statements best explains why the reaction described in Fact 3 requires a high temperature and pressure? A.All protons are positively charged, and like charges attract each other. B.All protons are positively charged, and like charges repel each other. C.All electrons are negatively charged, and like charges attract each other. D.All electrons are negatively charged, and like charges repel each other.

8. 9 th Grade Science #6. Based on Fact 5 and Student 1’s discussion, which of the 3 stars in the Algol system, if any, was most likely the first to become an MS star? A.Algol A B.Algol B C.Algol C D.The 3 stars became MS stars at the same time.

9. #7. Based on Fact 5, would Student 2 agree that by the time Algol A stops being an MS star, Algol A will have spent as much time being an MS star as Algol B spent being an MS star? A.Yes, because according to Student 2, Algol A has always been more massive than Algol B. B.Yes, because according to Student 2, Algol A has always been less massive than Algol B. C.No, because according to Student 2, Algol A has always been more massive than Algol B. D.No, because according to Student 2, Algol A has always been less massive than Algol B. 9 th Grade Science
