Scientists only speculate what dark matter ...c. a galaxy with constant mass density within 20,000 light-years of its center, and beyond that an enclosed mass that increases proportionally to the distance from the center …Final answer. Astronomical observations of our Milky Way galaxy indicate that it has a mass of about 8×1011 solar masses, A star orbiting near the galaxy's periphery is 5.9 ×104 light years from its center. (For your calculations, assume that the galaxy's mass is concentrated near its center.)

It’s a small part of the Milky Way Galaxy. A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems. A galaxy is held together by gravity. Our galaxy, the Milky Way, also has a supermassive black hole in the middle. When you look up at stars in the night sky, you’re seeing other stars in the Milky Way.

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).

The magnitude of the gravitational attraction between any of these points and the mass m is therefore the same. The net force between the hoop and mass m acts along the axis connecting the center of the shell and mass m. The area of the hoop is given by. Figure 14.2. Shell theorem. and its mass m is equal to.

Created by jordannowenss Terms in this set (133) How does the hypothesis of inflation account for the existence of the "seeds" of density from which galaxies and other large structures formed? Inflation would have caused random, microscopic quantum fluctuations to grow so large in size that they became the seeds of structure.

The vast majority of the galaxy’s mass is concentrated in a tiny region in its center, with mostly empty space outside of that region. B. The highest concentration of mass is in the center of the galaxy, and it decreases with increasing distance from the center. CORRECT C.Observations of the motions of stars in an elliptical galaxy have provided a velocity dispersion measurement of 200 km/s. Assume the measurements are made within a radius of 20 kpc from the center of the galaxy. You may find the worked example at the end of Section 8.4.2 helpful as you do this calculation.

Inflation was a dramatic expansion of the universe thought to have occurred when the universe was only a tiny fraction of a second old. 4. Olbers' paradox forces us to think about why the sky is dark at night. The Milky Way, an average spiral galaxy, spins at a speed of 130 miles per second (210 km/sec) in our Sun’s neighborhood. New research has found that the most massive spiral galaxies spin faster than expected. These “super spirals,” the largest of which weigh about 20 times more than our Milky Way, spin at a rate of up to 350 miles per ...The following theorem was proved by Newton in the Principia: A spherical mass can be thought of as built up of many infinitely thin spherical shells, each one nested inside the other. We will consider the gravitational attraction that such a shell exerts on a particle of mass m, a distance r from the center of the shell.For our calculation, then, we can assume that all the mass that lies inward of the Sun’s position is concentrated at the center of the Galaxy, and that the Sun orbits that point from a distance of about 26,000 light-years.

The rotation curve of a disc galaxy (also called a velocity curve) is a plot of the orbital speeds of visible stars or gas in that galaxy versus their radial distance from that galaxy's centre. It is typically rendered graphically as a plot, and the data observed from each side of a spiral galaxy are generally asymmetric, so that data from each ... integrator transfer function 1. The center of mass is defined as it is because the center of mass obeys Newton's second law. Consider a collection of particles, labeled by an index i. Then each particle obeys. F i = p ˙ i. We decompose the force into the interaction between particles and an external force. F i = ∑ j ≠ i F i j + F i ext.A. the center of mass of an object must lie within the object. B. all the mass of an object is actually concentrated at its center of mass. C. the center of mass of an object cannot move if there is zero net force on the object.
