Astronomy Unit 8 Exam - Questions & Answers Ranking Task: Understanding Curved Spacetime Part A: The figures below show several different astronomical
... [Show More] objects. Rank the objects based on the strength of the gravitational force that would be felt by a spacecraft traveling at a distance of 10 AU from the center of each of the objects, from weakest to strongest. If the gravitational force is equal for two (or more) cases, show this equality by dragging one figure on top of the other(s). All are the same. Ranking Task: Understanding Curved Spacetime Part B: The figures below show several different astronomical objects. Rank the objects based on the amount that spacetime is curved (relative to flat spacetime) at a distance of 10 AU from the center of each of the objects, from least to greatest. If two (or more) cases are equal, show this equality by dragging one figure on top of the other(s). All are the same. Ranking Task: Understanding Curved Spacetime Part C: The figures below show several different astronomical objects. Rank the objects based on the amount that spacetime is curved (relative to flat spacetime) very near the surface (or event horizon) of the objects, from least to greatest. -red giant -the Sun -white dwarf -black hole Ranking Task: Understanding Curved Spacetime Part D: The figures below show several different astronomical objects. Rank the objects based on the acceleration a spaceship would have as it passed very near the surface (or event horizon) of each object, from smallest to largest. -red giant -the Sun -white dwarf -black hole Sorting Task: Effects of Relativity Imagine that you are located on Earth while a spaceship travels from Earth to the star Vega at constant velocity of 0.8c. The following items describe quantities that, according to Einstein's special theory of relativity, would be either larger (or longer), smaller (or
shorter), or the same as their rest values. (Note that by "rest value," we mean the value you would find if both you and the spaceship [Show Less]
