Question

Question 2) This problem will be about the skill of problem-solving. This semester you will be learning both astronomy as well as problem-solving so we need to study this too. Consider the following problem: "Using size balance (pressure vs. gravity) and temperature balance (energy created vs. energy lost), explain why being a more massive star causes it to be more luminous than a less massive star." From the underlined problem give me the following: A) what is the actual question being asked, B) what does the word than' tell us about this problem, C) where should you start your answer, D) where should you end your answer, E) what is the hint in this problem, and F) what purpose do the parenthesis serve? Please note that I'm not asking you to answer the underlined problem, but instead to analyze how you would go about the answering process. [Hint: from the words, we can tell this is a cause-and-effect problem, so what does that say about where to start and where to finish?]

Explanation / Answer

A) The actual question is whether the less massive or more massive star is luminous. B) The word than means more luminous. The luminousity in less or more massive star. C) The answer will be started using pressure gravity balance concept. D) The answer will be ended by proving that the massive star is more luminous.
