Consider any star on a circular orbit around the center of the galaxy. The speed of the star's orbit depends on the star's distance from the galactic center and __________. the mass …(c) An isolated spherical planet of radius R may be assumed to have all its mass concentrated at its centre. The gravitational potential at the surface of the planet is − 6.30 × 107 J kg −1. A stone of mass 1.30 kg is travelling towards the planet such that its distance from the centre of the planet changes from 6R to 5R.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 ...

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 ... Galaxies are large systems of stars, gas, dust and dark matter that orbits a center and is bound by gravity. Learn about the characteristics of galaxies. Advertisement When you look up at the night sky, especially during the summer, you'll ...Studying dark matter in distant galaxies. Dark matter makes up approximately 84% of the mass in the cosmos: "Its dominant presence throughout the galaxies arises from the fact that the stars and ...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.

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.

Question: Understand that, for many purposes, a system can be treated as a point-like particle with its mass concentrated at the center of mass. A complex system of objects, both point-like and extended ones, can often be treated as a point particle, located at the system's center of mass. Such an approach can greatly simplify problem solving.Study with Quizlet and memorize flashcards containing terms like Process of Science: Composition of the Universe Part A: Because the original assumption about all matter interacting with electromagnetic radiation was proved incorrect for the Milky Way Galaxy, scientists next need to determine whether the assumption still holds true for other galaxies. To do this, scientists need a way to ...
