Lunar astronauts placed a reflector on the Moon’s surface, off which a laser beam is periodically reflected. The distance to the Moon is calculated from the round-trip time. (a) To what accuracy in meters can the distance to theMoon be determined if this time can be measured to 0.100 ns? (b) What percent accuracy is this, given the average distance to the Moon is 384,400 km?

Radio-controlled clocks throughout the United States receivea radio signal from a transmitter in Fort Collins, Colorado,that accurately (within a microsecond) marks the beginningof each minute. A slight delay, however, is introducedbecause this signal must travel from the transmitter to theclocks. Assuming Fort Collins is no more than 3000 km fromany point in the U.S., what is the longest travel-time delay?
