Solved At The Galaxy S Core Astronomers Have Observed A Chegg At the galaxy's core. astronomers have observed a small, massive object at the center of our milky way galaxy a ring of material orbits this massive object; the ring has a diameter of about 15 light years and an orbital speed of about 200 km s. (a) determine the mass of the object at the center of the milky way galaxy. 1 3. 4 3 * at the galaxy's core. astronomers have observed a small, massive object at the center of our milky way galaxy (see section 1 3. 8). a ring of material orbits this massive object; the ring has a diameter of about 1 5 light years and an orbital speed of about 2 0 0 k m s.
Solved At The Galaxy S Core Astronomers Have Observed A Sm C) they are moving away from earth and are closer to earth than galaxies with high speeds. suppose that galaxy b is twice as far from earth as galaxy a. hubble's law predicts that galaxy b will be moving away from earth with approximately . a) the same velocity as galaxy a. b) four times the velocity of galaxy a. A: astronomers can calculate mass in several ways. the simplest is when the object is part of a binary system. regardless of the objects in the binary — two stars, a star and a neutron star, a. A line in the spectrum of a galaxy is at a wavelength of 393 nanometers (nm, or 10 –9 m) when the source is at rest. let’s say the line is measured to be longer than this value (redshifted) by 7.86 nm. then its redshift z = 7.86 nm 393 nm = 0.02 z = 7.86 nm 393 nm = 0.02, so its speed away from us is 2% of the speed of light (v c = 0.02. Astronomers have observed a small, massive object at the center of our milky way galaxy (see section 13.8 ). a ring of material orbits this massive object; the ring has a diameter of about 15 light years and an orbital speed of about 200 $\mathrm{km} \mathrm{s} .$ (a) determine the mass of the object at the center of the milky way galaxy.
