Astro 7n Exam 1 Questions with 100%Correct Answers 2024. 1. What two properties of a planet affect the gravity we feel on its surface? A: radius and distance from the Sun B: radius and temperature C: mass and distance from the Sun D: mass and radius E: mass and temperature 2. Two planets have the same radius. If Planet A is 5 times more massive than Planet B, how does gravity differ on the surfaces of the two planets? A: gravity is 5 times stronger on Planet B B: gravity is 5 times stronger on Planet A C: gravity is 25 times stronger on Planet A D: gravity is 25 times stronger on Planet B E: gravity is equal on Planet A and Planet B 3. Say that there were a planet X in our Solar System with a mass 1/4 the mass of Earth and a radius 1/2 the radius of Earth. How will the gravity on its surface compare to the surface gravity of Earth? A: surface gravity on planet X is 2 times weaker than on Earth B: surface gravity on planet X is 2 times stronger than on Earth C: surface gravity on planet X is the same as on Earth D: surface gravity on planet X is 8 times stronger than on Earth E: surface gravity on planet X is 4 times weaker than on Earth 4. A planet in a nearly circular orbit with its rotation axis tilted by 5 degrees relative to its orbital plane around its star would ... A: have longer days and nights than those of Earth B: have very severe seasons compared to Earth C: have shorter years than those of Earth D: have shorter days and nights than those of Earth E: have seasons that are not very different from each other as compared tEarth's. Astro 7n Exam 1 Questions with 100%Correct Answers 2024 5. The rotation axis of the Earth is ... A: tilted so that it is always pointed directly at the Sun B: is sometimes parallel and sometimes perpendicular to the axis of the Earth's orbit around the Sun. C: tilted at about 23 degrees relative to the axis of the Earth's orbit aroundSun. D: perpendicular to the axis of the Earth's orbit around the Sun. E: parallel to the axis of the Earth's orbit around the Sun. 6. In the diagram above, what season and planet is being represented by the red X on the planet on the left in orbit around the Sun? A: winter on Earth B: summer on Earth C: winter on Venus D: winter on Uranus E: summer on Uranus 7. When is the waning gibbous moon highest in the sky? A: about 9:00am B: about 3:00am C: about noon D: about midnight E: about 3:00pm.
