You send a flash of light toward the Moon. It bounces off a mirro measure the time between when you sent the flash and when it returns to you and find that the whole process took 2.0 seconds. The distance to the Moon is (state vour answer in kilometers and list the answer with at least three significant figures.) You can use 3x108 m/s as the speed of light (feel free to google this quantity to verify). a r and...
