Time standards are now based on atomic clocks. A promisingsecond standard is based on pulsars, which arerotating neutron stars (highly compact stars consisting only ofneutrons). Some rotate at a rate that is highly stable, sending outa radio beacon that sweeps briefly across Earth once with eachrotation, like a lighthouse beacon. Suppose a pulsar rotates onceevery 1.743 206 448 872 75 ± 2 ms, where thetrailing ± 2 indicates the uncertainty in the lastdecimal place (it does not mean ± 2ms).
How many rotation does the pulsar makein 14.0 days?(b) How much time does the pulsar take to rotate exactly onemillion times? (Give your answer to at least 4 decimal places.)
(c) What is the associated uncertainty?
