Concept explainers
Explain all answers clearly, using complete sentence and proper essay structure if needed. An asterisk (*) designates a quantitative problem, for which you should show all your work.
Galactic Rotation. Our solar system is located about 27,000 light-years from the galactic centre and orbits the centre once every 230 million years. How fast are we travelling around the galaxy, in km/hr?
