Theoretical models of the slowing of pulsars predict that the age of a pulsar is approximately equal to p/2r, where p is the pulsar’s current period and r is the rate at which the period is slowing with time. Observations of the pulsar in the Crab Nebula show that it pulses 30 times a second, so p = 0.0333 second, but the time interval between pulses is growing longer by 4.2 * 10–13 second with each passing second, so r = 4.2 * 10–13 second per second. Using that information, estimate the age of the Crab Nebula pulsar. How does your estimate compare with the true age of the pulsar, which was born in the supernova observed in a. d. 1054?

may have one traffic conviction within 12 months from the issue date of the learner's license if adjudication is withheld.
