Each time the pulsar makes one revolution, the rotating beam sweeps across the earth, and the earth receives a

Question

(continues question) a pulse of radio waves. For one particular pulsar, the time between two successive pulses is 0.044 s. Determine the average angular speed (in rad/s) of this pulsar.

Answer 1

Rads is short for radiuses. The question is 'How many radiuses will the pulsar turn per second?'

Now remember the circumfirance of a circle is c= 2*pi*r

Therefore the average angular speed is

= 2 * pi * rads/ .044 sec
=(2 *pi)/(.044) * rads/sec
= 142.8 rads/sec
