A pulsar rotates once every 1.610 968 948 872 75 ± 2 ms, where thetrailing ± 2 indicates the uncertainty in the last decimal place(it does not mean ± 2 ms).
(a) How many times does the pulsar rotate in 21.0 days?


(b) How much time does the pulsar take to rotate exactly onemillion times? (Give your answer to at least 4 decimalplaces.)


(c) What is the associated uncertainty of this time?

A pulsar is a rapidly rotating neutron star that emits a radiobeam the way a lighthouse emits a beam of visible light. We observea radio pulse each time the star makes one rotation. The period ofthe pulsar is then simply the time between the observed pulses. Thepulsar in the Crab Nebula has a period of rotation of which isincreasing at a rate of .

a) What is the pulsar’s angular acceleration (in 2010)?

b) If the pulsar began rotating in 1054 after the supernovae whichbirthed it, what was its angular velocity then?

c) In how many years will the pulsar stop rotating?

Note: DO NOT ASSUME A CONSANT ANGULAR ACCELERATION!

A pulsar is a rapidly rotating neutron star that emits a radio beamthe way a lighthouse emits a light beam. We receive a radio pulsefor each rotation of the star. The period T of rotation is found bymeasuring the time between pulses. Suppose a pulsar has a period ofrotation of T = 0.0841 s that is increasing at the rate of 2.16 x10-6 s/y. (a) What is the pulsar's angular acceleration ? (b) If isconstant, how many years from now will the pulsar stop rotating?(c) Suppose the pulsar originated in a supernova explosion seen1160 years ago. Assuming constant , find the initial T.
