Time standards are now based on atomic clocks. A promisingsecond standard is based on pulsars, which are rotatingneutron stars (highly compact stars consisting only of neutrons).Some rotate at a rate that is highly stable, sending out a radiobeacon that sweeps briefly across Earth once with each rotation,like a lighthouse beacon. Suppose a pulsar rotates once every 1.743206 448 872 75 ± 2 ms, where the trailing ± 2 indicates theuncertainty in the last decimal place (it does not mean ±2 ms).
How many rotation does the pulsar make in 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?
