Conservation of angular momentum A spherical star with radius R1 7.96 x 10 km and rotating with angular speed (o 3,92 x 10s rad/s suddenly collapses into a neutron star. The neutron star emits a beam of X-rays directed radially outward that can be seen by an observatory on the earth r 4.55 x 104 km from the star. The X-ray beam sweeps past the earth with a tangential speed v 7.40 x 10 km/s each...

PartA Constants Suppose a star the size of our Sun, but with mass 9.0 times as great, were rotating at a speed of 1.0 revolution every 10 days. If it were to undergo gravitational collapse to a neutron star of radius 12 km, losing three-quarters of its mass in the process, what would its rotation speed be? Assume also that the thrown-off mass carries off either no angular momentum Express your answer using two significant figures. A2c rev/s Part B...
