Question 1: Score 0/1 Ceres, the largest asteroid known, has a mass of roughly 8.7E20 kg. If Ceres passes within 12,000.0 km of the spaceship in which you are traveling, what force does it exert on you? (Use an approximate value for your mass, and treat yourself and the asteroid as point objects.) Enter scientific notation as 1.23E4. Your Answer: 3.4E5 N Correct Answer: 0.026±0.002 N [2 significant digits required] Question 2: Score 0/1 Several volcanoes have been observed erupting on the surface of Jupiter’s closest Galilean moon, Io. Suppose that material ejected from one of these volcanoes reaches a height of 5.90 km after being projected straight upward with an initial speed of 146 m/s. Given that the radius of Io is 1820.0 km, calculate Io's mass. Enter scientific notation as 1.23E4. Your Answer: 8.61E5 kg Correct Answer: 8.92E22±2E20 kg [3 significant digits required] Question 3: Score 0.33/1 Two satellites orbit the Earth, with satellite 1 at a greater altitude than satellite 2.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
