After our Sun exhausts its nuclear fuel, its ultimate fate may be to collapse to a white dwarf state, in which it has approximately the same mass as it has now but a radius equal to roughly the size of the Earth's radius. (a) Calculate the average density of this white dwarf if the Sun were to collapse to a radius of 6.01 x 106m. kg/m3 (b) Calculate the free-fall acceleration at its surface. m/s? (c) Calculate the gravitational potentiatenergy of a 1.00 kg object at its surface. (Take U, - 0 at infinity.)

A neutron star is an astrophysical object having a mass of roughly 2.8 × 1030 kg (about 1.4 times the mass of the sun) but a radius of only about 12 km. If you were in a circular orbit of radius 320 km (about 200 mi), how long would it take you to go once around the star? It would take about _______ s to go once around the star.

Black holes are difficult to observewith telescopes because they, bydefinition, don’t emit or reflect any light. They can be found by look-ing for other nearby objects orbit-ing them, however. Here is a dia-gram of a star in a circular orbit around a black hole. a. The period of the star’s orbit is 90 days, and its orbital radius around the black hole isobserved to be 3.6 : ×10^11 m. Find the orbital velocity of the star in units of m/s. (You need to convert 90 days to seconds, first). The circumference of a circle is 2πr. b. The mass of the star is known to be 4 × 10^30 kg. Find the centripetal acceleration of thestar and the strength of the gravitational force on the star. c. Find the mass of the black hole.
The evolution of a star depends on its size. If a star is sufficiently large, the gravity forces holding it together may be large enough to collapse it into a very dense object composed mostly of neutrons. The density of such a neutron star is about 1014 times that of the Earth. Suppose that a star initially had a radius of 7 x 108 km, and it rotated once every 26 days. What would be the period of rotation if the star collapsed to a radius of 15 km? (1.19 x 10-14 days)
The Schwarzschild radius is a distance from a black hole where the escape velocity equals the speed of light (even light cannot escape from a black hole). Determine the Schwarzschild radius for a black hole with the mass of the Sun.
