Question
neuton stars are what are left over after some of the large supernovas explode. these are very small and very massive stars rotate very fast and maintian speed by conservation of angular momentum. a glitch occurs when a neuron star suddenly spin faster during the glitch the angular momentum is conserved. use this fact and the data below to find out how much the radius of the neuron star changes due to the high glitch.
pre glitch angular velocity:wo
post glitch angular velocity : 1.000001wo
neutron star radius: 5 km
neutron star mass : 2.2 times the mass of the sun.
assume that the neutron star is spherical before and after the glitch
hint: consider that you wil need the moment of intertia of that spherical neutron star both before and after the glitch.
Explanation / Answer
angular momentum L = r*m*v
v=r*angular velocity
conservation
r*r*m*w=r*r*m*1.000001w
r*r=5*5*1.000001
r=5.0000025km
change=.0025m
