True or False (Explain if False) 1. Joseph Musk launches two satellites of different masses to orbit the Earth circularly on the same radius. The two satellites have different but proportional speeds. 2. Another of the 14 moons of Neptune is named Galatea,  which accelerates slower than the planet. 3.
