Solve the all given part of following question:
Question: Time standards are now based on atomic clocks. A promising second standard is based on pulsars, which are rotating neutron stars (highly compact stars consisting only of neutrons). Some rotate at a rate that is highly stable, sending out a radio beacon that sweeps briefly across Earth once with each rotation, like a lighthouse beacon. Suppose a pulsar rotates once every 1.587 343 948 872 75 ± 4 ms, where the trailing ± 4 indicates the uncertainty in the last decimal place (it does not mean ± 4 ms).
Part A: How many times does the pulsar rotate in 7.00 days?
Part B: How much time does the pulsar take to rotate exactly one million times? (Give your answer to at least 4 decimal places.) s
Part C: What is the associated uncertainty of this time? ± s
Explain the each and every step in derail for help. Thanks.
