ASTRO 7N 7N - Pennsylvania State University, Astro 7N Exam 1 What two properties of a planet affect the gravity we feel on its surface? Two planets have the same radius. If Planet A is 5 times more mass than Planet B, how does gravity differ on the surfaces of the two planets? 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 planet...

Module B Learning Outcomes summary study guide complete and verified 100% Summarize the historical sources of diamond prior to 1867 - -Historically, diamonds were extremely rare and sourced from only a few scattered alluvial (i.e., within river gravels) localities. They were *first discovered in the Golconda Region of India* and then *subsequently in Brazil* by the 18th century. It has been supposed that a maximum 50,000 carats could have been produced annually from India before the 18th...
