The third method astronomers use to detect and measure dark matter in galaxy clusters is to image them in the light of X-rays. When the first sensitive X-ray telescopes were launched into orbit around Earth in the 1970s and trained on massive galaxy clusters, it was quickly discovered that the clusters emit copious X-ray radiation (see Figure 28.25).Step-by-step explanation. It is stated that within the 20,000 light-years from the galactic center the galaxy would have a constant density and beyond 20,000 light-years it would have zero density. Because of this condition we can say that the distance beyond 20,000 light-years will have a drop in the orbital speed but as it drop the orbital ...

A classic problem in mechanics is the calculation of the gravity force that would be experienced by a mass m that was attracted by a uniform spherical shell of mass M. The law of gravity applies, but calculus must be used to account for the fact that the mass is distributed over the surface of a sphere. The problem is envisioned as dividing an ...

Figure 4.3.4 4.3. 4: The nuclear atom. The nucleus of the atom is extremely small. Its radius is only about 1/100,000 of the total radius of the atom. Electrons have virtually no mass, but protons and neutrons have a lot of mass for their size. As a result, the nucleus has virtually all the mass of an atom.

The Sun, like all the other stars in the Galaxy, orbits the center of the Milky Way. Our star's orbit is nearly circular and lies in the Galaxy's disk. The speed of the Sun in its orbit is about 200 kilometers per second, which means it takes us approximately 225 million years to go once around the center of the Galaxy.Textbook solution for The Cosmic Perspective (8th Edition) 8th Edition Jeffrey O.
