After the Sun exhausts its nuclear fuel, its ultimate fate may be to collapse to a white dwarf state. In this state, it would have approximately the same mass as it has now, but its radius would be equal to the radius of the Earth. (a) Calculate the average density of the white dwarf. Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. kg/m3 (b) Calculate the surface free-fall acceleration. Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. m/s2 (c) Calculate the gravitational potential energy associated with a 6.69-kg object at the surface of the white dwarf. The response you submitted has the wrong sign. J

What is the acceleration of gravity at the surface if the white dwarf has 1.5 the mass of the sun and is only half the radius of earth?
Say that a particular white dwarf has the mass of the Sun but the radius of Earth. What is the acceleration of gravity at the surface of the white dwarf? How much greater is this than g at the surface of Earth? What would you weigh at the surface of the white dwarf (again granting us the dubious notion that you could survive there)?
The star HD 69830's mass is 1.7 ✕ 1030 kg, its radius is 6.3 ✕ 105 km, and it has a rotational period of approximately 35 days. If HD 69830 should collapse into a white dwarf of radius 7.8 ✕ 103 km, what would its period (in s) be if no mass were ejected and a sphere of uniform density can model HD 69830 both before and after?
After the Sun exhausts its nuclear fuel, its ultimate fate may be to collapse to a white dwarf state. In this state, it would have approximately the same mass as it has now, but its radius would be equal to the radius of Earth. Calculate (a) the average density of the white dwarf, (b) the surface free-fall acceleration, and (c) the gravitational potential energy associated with a 1.00-kg object at the surface of the white dwarf.
Based on the problem attached, what is the answer for sub-item (b) if the radius of the neutron star is 67.004 km? (express your answer in the proper SI unit and without scientific notation)
what is the answer for sub-item (b) if the radius of the neutron star is 6.676 km? (express your answer in the proper SI unit and without scientific notation) (b)What is the average density of a neuron star that has the same mass as the sun but a radius of only 20.0 km?
Suppose we represent an ordinary star as a uniform solid rigid sphere. The star’s initial radius is 644000 km (comparableto the size of our sun). After it collapses, forming a neutron star, its final radius is only 18.3 km! If the original starmakes one complete rotation about its axis once per month (every 30 days), find the neutron star’s period of rotationjust after the original star has collapsed.Tafter = (in s)
what is the answer for sub-item (b) if the radius of the neutron star is 47.545 km? (express your answer in the proper SI unit and without scientific notation)
What is the escape velocity (in km/s) at the Schwarzschild radius of a 7.82 Msun black hole?
What is the escape velocity Vesc of a 1.4M⊙ neutron star if its radius is 12 km? Express your answer as a multiple of the speed of light (i.e., compute Vesc/c, where c= 2.9979 x 105 km/s). [Hint: you will need to recall the formula for escape speed from the surface of an object. This was discussed when we covered planetary atmospheres.]
If the Sun were to collapse into a black hole, the point of no return for an investigator would be approximately 3 km from the center singularity. Would the investingator be able to survive visiting even 300 km from the center? Answer this by finding the difference in the gravitatoinal attraction the black holes exerts on a 1.0-kg mass at the head and at the feet of the investigator.
