A pulsar rotates once every 1.610 968 948 872 75 ± 2 ms, where thetrailing ± 2 indicates the uncertainty in the last decimal place(it does not mean ± 2 ms).
(a) How many times does the pulsar rotate in 21.0 days?
(b) How much time does the pulsar take to rotate exactly onemillion times? (Give your answer to at least 4 decimalplaces.)
(c) What is the associated uncertainty of this time?
