To do this, scientists need a way to ... Astronomical observations of our Milky Way galaxy indicate that it has a mass of about 8·x 1011 solar masses. A star orbiting near the galaxy's periphery is 5.8 x 104 light years from its center. (For your calculations, assume that the galaxy's mass is concentrated near its center.) Gradually, starlight that was once concentrated at the center would spread out into a broader, diffuse core, with a little kink at the center where the black-hole binary was doing its mating dance ...If the mass of a 1 cm by 1 cm square is 1 unit, then the mass of the left subsystem is 72 units and the mass of the right subsystem is 32 units. We find the CM of the system by treating each subsystem as a separate particle, with all its mass concentrated at its center of mass. Then we have for the whole system; Details of the calculation:

(i) A rock of mass 4.50 kg is situated on the surface of the Moon. Show that the changeThe estimate is based on observations showing that most of the galaxy’s mass is concentrated in the interior. In this configuration a “Keplerian” model is applied (a bit like the solar system which has its mass concentrated in the sun) which predicts that the rotation speed is proportional to 1/√r , that is, it decreases as the distance ...The halo's greatest concentration is at its center, where the cumulative light of its stars becomes comparable to that of the disk stars. This region is called the (nuclear) bulge of …

If you look at a system in which almost all the mass is concentrated at the center -- like our Solar System -- then the speed with which objects orbit the system decreases quickly with distance. Specifically, the orbital speed goes as the inverse square root of the orbital radius; we call this common situation "Keplerian rotation."$\begingroup$ Since the alpha particles rebounded in many of the cases it is certain that most of the positive charge was concentrated in a small volume. What puzzles me is how was it ascertained that that same region which contained the positive charge was also the one which carried most of the mass of the atom.Expert Answer.

The authors find that the mass of the galaxy is 0.21 x 10 12 solar masses, the circular velocity of the galaxy at the maximum radius they look at (21.1 kpc) is 206 km/s, and the virial radius is 1.28 x 10 12 solar masses. This virial mass fits in most with intermediate values found by other studies. Recasting the equation given above (for the determination of the mass in a galaxy), we find Mass = 9x10 10 (speed/220 km/s) 2 (orbit/25,000 ly) Solar masses. The mass contained in the Milky Way galaxy (in its visible disk) is then 2x10 11 Solar masses.
