A pulsar is a rapidly rotating neutron star that continuously emits a beam of radio waves in a searchlight manner. Each time the pulsar makes one revolution, the rotating beam sweeps across the earth, and the earth receives a pulse of radio waves. For one particular pulsar, the time between two successive pulses is 0.0348 s. Determine the average angular speed (in rad/s) of this pulsar.

    2 pi radians/0.0348 s = 180.6 rad/s
