Textbook Question

Chapter 1, Problem 16P

White dwarfs and neutron stars. Recall that density is mass divided by volume and consult Chapter 0 and Appendix E as needed, (a) Calculate the average density of the earth in g/cm³, assuming our planet to be a perfect sphere, (b) In about 5 billion years, at the end of its lifetime, our sun will end up as a white dwarf, having about the same mass as it does now, but reduced to about 15.000 km in diameter. What will be its density at that stage? (c) A neutron star is the remnant left after certain supernovae (explosions of giant stars). Typically, neutron stars are about 20 km in diameter and have around the same mass as our sun. What is a typical neutron star density in g/cm³?

Can you please help w/ the question in the pic? This is the data I have so far: 1. Determine the mass M of the massive object at the center of the Milky Way galaxy. Take the distance of one light year to be 9.461x10^15: answer= 4.26*10^37 2.Express your answer in solar masses instead of kilograms, where one solar mass is equal to the mass of the sun, which is 1.99*10^30: answer=2.14*10^7 TIA

A star, which is 2.3 x 1020 m from the center of a galaxy, revolves around that center once every 2.3 x 10% years. Assuming each star in the galaxy has a mass equal to the Sun's mass of 2.0 x 1030 kg, the stars are distributed uniformly in a sphere about the galactic center, and the star of interest is at the edge of that sphere, éstimate the number of stars in the galaxy. Number i Units

ASK YOUR TEACHER PRACTICE ANOTHER Since neutron stars consist totally of neutrons, they are extremely massive and have a density that is hard to imagine. A typical radius and mass for a neutron star are 1.65 x 10 m and 2.50 x 1028 kg respectively. (a) Determine the density of a neutron star. kg/m (b) Determine the weight (in pounds) of a penny (V = 360 mm-) if it were made from this material. (Assume 1 lb = 4.448 N.) Ib Additional Materials
