SOLVED: The stability of the cesium clock used as an atomic time standard is such that two cesium clocks would gain or lose 1  s with respect to each other in about 300,000 y. If this same precision were applied to the distance between New York and San Francisco ( 2572 mi ), by how much would successive measurements of this distance tend to differ? | Numerade
