A galaxy with all its mass concentrated at its center.
Figure 28.4.1 28.4. 1 Rotation Indicates Dark Matter. We see the Milky Way’s sister, the spiral Andromeda galaxy, with a graph that shows the velocity at which stars and clouds of gas orbit the galaxy at different distances from the center (red line). As is true of the Milky Way, the rotational velocity (or orbital speed) does not decrease ...Astronomers observe two galaxies. A and B. A has a recession velocity of 1500km/s, while galaxy B has a recession velocity of 3000km/s. This means that: Galaxy B is twice as far away as galaxy A. In every direction that astronomers look, they see the same Hubble's law, with the same slope. This is an example of.

Expert Answer. Most of the light of our galaxy is concentrated at the center; if most of the MASS were concentrated there, too, then the gravitational force on stars far from the …a. a galaxy with all its mass concentrated at its center b. a galaxy with constant mass density within 20,000 light-years of its center, and zero density beyond that distance 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 centerDefinition. The center of mass is the unique point at the center of a distribution of mass in space that has the property that the weighted position vectors relative to this point sum to zero. In analogy to statistics, the center of mass is the mean location of a distribution of mass in space.

A rock of mass 1.40 kg rests on the surface of Mars. For this rock, (a) (i) determine its weight,Summary. The Sun revolves completely around the galactic center in about 225 million years (a galactic year). The mass of the Galaxy can be determined by measuring the orbital velocities of stars and interstellar matter. The total mass of the Galaxy is about 2 × 10 12 M Sun.Its mass is assumed to be concentrated at its centre. Given that the gravitational field strength at the Earth’s surface is 9.81 N kg–1, show that the mass of the Earth is 5.99 × 1024 kg. (b) A satellite is placed in geostationary orbit around the Earth. (i) Calculate the angular speed of the satellite in its orbit.Measurement of the cosmic microwave background shows that 80 percent of the total mass of the Universe is made of dark matter, but this can’t tell us exactly where that matter is distributed ...

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. This is the sort of situation to which Kepler 's third law (as modified by Newton) can be directly applied.... of the sun.

The third ...
alax math Its closest approach takes it to a distance of only 124 AU or about 17 light-hours from the black hole. This orbit, when combined with observations of other stars close to the galactic center, indicates that a mass of 4.6 million M Sun must be concentrated inside the orbit—that is, within 17 light-hours of the center of the Galaxy.The Sun revolves completely around the galactic center in about 225 million years (a galactic year). The mass of the Galaxy can be determined by measuring the orbital velocities of stars and interstellar matter. The total mass of the Galaxy is about 2 × 10 12 M Sun. As much as 95% of this mass consists of dark matter that emits no ... fang osrs pricecrossword jam level Advanced Physics questions and answers.

Combined with other kinematic information about these stars, the scientists calculate that the mass of the galaxy is between 1.2 and 1.9 trillion solar masses, adding significant precision to the previous estimates. "Constraining Milky Way Mass with Hypervelocity Stars," G. Fragione and A. Loeb, A&A, in press (2017). limestone geology Use Newton's Law of Gravitation to compute the work (in J) required to launch a 1000-kg satellite vertically to an orbit 1000 km high. You may assume that Earth's mass is 5.98×1024kg and is concentrated at its center. Take the radius of the Earth to be 6.37×106m and G=6.67×10−11N⋅m^2/kg^2. Relevant Equations land for sale tennessee zillowspectrum customer service hawaiiwhat time is ku game saturday 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 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. fitness degrees online This behavior contrast sharply with the steeply declining orbital speeds in the solar system, leading us to conclude that most of the Milky ways mass must not be concentrated at its center instead, The orbital speeds in the Milky Way imply that most of our galaxy's mass lies well beyond the orbit of our sun. power strip to extension cordkansas v oklahomaarkansas vs kansas football A) It will collide with stars in the Andromeda galaxy. B) It will collide with stars in both the Andromeda and Milky Way galaxies. C) It will be swallowed by the supermassive black hole at the galactic center. D) It will collide with stars in our own Milky Way galaxy. E) It will immediately go supernova.
