I'm doing my physics homework online, and this unit conversion problem is getting to me. Here it is along with my work.
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 1.342 806 448 872 75 6 ms, where the trailing 6 indicates the uncertainty in the last decimal place (it does not mean 6 ms).
Now my thoughts:
It rotates one time every 1.342806448872756ms, so I need to convert this to one # of times per 30 days.
which equals 3480554315 times, which is incorrect. I know I'm having a brain fart. Someone tell me what it is.
