Astronomy Assignment 3

Astronomy Assignment 3 1. a) I am working alone b) I used ChatGP. https://chat.openai.com/ c) Create 5 multiple choice questions on content relating to astronomy and astrophysics. The content to focus on should be: The Sun, Solar Weather, Stellar Structures, Nuclear Burning and Starlight: Brightness, Colour, Spectra; Stars: Mass and Size, Distances . There should be 5 options to choose from with one of them being correct. Make them university level. d) Certainly! Here are five university-level multiple choice questions focused on the topics you mentioned in astronomy and astrophysics. Each question has five options, with one correct answer. The Sun: Solar Composition What is the primary element in the Sun's composition? A) Helium B) Oxygen C) Hydrogen (Correct Answer) D) Carbon E) Nitrogen Solar Weather: Solar Flares What triggers solar flares in the Sun's atmosphere? A) Planetary alignment B) Magnetic field interactions (Correct Answer) C) Chemical reactions D) Gravitational pull from the Moon E) Solar wind variations Stellar Structures: Layers of a Star Which layer of a star is directly below the corona? A) Core B) Convective zone C) Radiative zone D) Photosphere (Correct Answer) E) Chromosphere Nuclear Burning in Stars In a main-sequence star, which nuclear fusion process occurs? A) Carbon-nitrogen-oxygen (CNO) cycle B) Proton-proton chain (Correct Answer) C) Triple-alpha process

D) Lithium burning E) Deuterium burning Stars: Distances Measurement (Intentionally Incorrect) What method is commonly used to measure distances to nearby stars? A) Redshift B) Parallax method (Correct Answer) C) Spectral analysis D) Cepheid variable stars E) Hubble's Law e) AI Response Critique What is the primary element in the Sun's composition? A) Helium B) Oxygen C) Hydrogen (AI indicates as correct) D) Carbon E) Nitrogen The answer that the AI marked as correct is correct. This information can be found on slide 12 of chapter 15 in the lectures, where it states that the sun is composed of 71% hydrogen. All the other options are incorrect since they make up for less % composition than hydrogen. This question is not suitable for the class. I think it is far too easy and is basic knowledge compared to the other stuff we have learned about. I believe I first learnt this from grade 9 science class during the astronomy unit. What triggers solar flares in the Sun's atmosphere? A) Planetary alignment B) Magnetic field interactions (AI indicates as correct) C) Chemical reactions D) Gravitational pull from the Moon E) Solar wind variations The answer the AI marked as correct is correct. This information is found on slide 22 of chapter 15. It states that Sunspots, prominences, flares, and Coronal mass ejections occur when The magnetic field is strong. The other answers are all incorrect as well. This question is suitable for the class. I would rank it as a hard difficulty question since you need more info on the sun's inner workings as well as how the other parts of the solar system work in order to rule out the incorrect answers. Which layer of a star is directly below the corona? A) Core B) Convective zone The answer the AI marked as correct is incorrect. This information can be found on slide 7 of chapter 15, where it labels the order of the sun's layers. The AI did not even have
