A galaxy with all its mass concentrated at its center.

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. Plugging ...

$\begingroup$ 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.See full list on courses.lumenlearning.com By comparison, our own Milky Way has at its center a massive black hole only 4 million times the mass of the sun. They also were able to measure the rotation of the galaxy, which is a relatively ...A star orbiting on the galaxy's periphery is about 6.0 \times 10^4 6.0×104 light years from its center. (a) What should the orbital period of that star be? (b) If its period is 6.0 \times 10^7 \textrm { y} 6.0×107 y instead, what is the mass of the galaxy? Such calculations are used to imply the existence of “dark matter” in the universe ...Evidence for an Intermediate Mass Milky Way. 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.Question: Select the approximate graph showing how orbital speed depends on distance from the galactic center for each of the following three hypothetical galaxies A galaxy …

So we see that the cylinder with its mass concentrated at its center wins the race, followed by the disc, with the hoop coming last, with their final velocities in the ratio of about 1.4:1.2:1. We also see that our results are independent of the masses of the cylinders. What they do depend on, however, is the way the mass of the cylinders is ...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 ...The Milky Way Galaxy’s structure is fairly typical of a large spiral system. (Spiral galaxies and other types of galaxies are described in the article galaxy.)This structure can be viewed as consisting of six separate parts: (1) a nucleus, (2) a central bulge, (3) a disk (both a thin and a thick disk), (4) spiral arms, (5) a spherical component, and (6) a massive halo.Since gravity depends on mass and distance, knowing the size of the star orbits enables you to derive the galaxy's mass. For spiral galaxies the rotation curve is used to measure their masses like is done to find the mass of the Milky Way. The rotation curve shows how orbital speeds in a galaxy depend on their distance from the galaxy's …Advanced Physics questions and answers.

Medium. Solving time: 3 mins. An isolated planet may be assumed to be a uniform sphere of radius 3.39× 106 m with its mass of 6.42× 1023 kg concentrated at its centre. Calculate the gravitational field strength at the surface of the planet. Views: 5,767 students.The mass of the planet, assumed to be concentrated at its centre, is 7.5 × 1023 kg. The radius of the planet is 3.4 × 106 m. (i) The spacecraft is to orbit the planet at a height of 2.4 × 105 m above the surface of the planet. At this altitude, there is no atmosphere. Show that the speed of the spacecraft in its orbit is 3.7 × 103 m s –1. [2]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. Newton’s 2nd law relates force to acceleration. In the angular version of Newton’s 2nd law, torque τ takes the place of force and rotational inertia takes the place of mass. When the rotational inertia of an object is constant, the angular acceleration is proportional to torque. For example, if we attach a rotating disc to a massless rope ...Answer all the questions in the spaces provided. 1 (a) The Earth may be considered to be a uniform sphere of radius 6.37 × 103 km with its mass of 5.98 × 10 24 kg concentrated at its centre.

To do this, scientists need a way to ...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.The material has uniform density so the mass is proportional to the area. For simplicity we can represent the mass of each section in units of 'squares' as shown in the diagram.

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.
