Galaxies contain both stars and dark matter. the mass m of a galaxy that is located within a certain star's orbit is given by where v is the velocity of the star, r is the distance from the galaxy's center to the star, and g is newton's gravitational constant, 6.673 x 10- n m/kg stars near the edge of a particular galaxy have velocities of 259 km/s. the radius of the galaxy is 53 kpc. how much mass is in the galaxy? galaxy = kg if luminous matter makes up 7.0% of the mass in the galaxy. how much mass is in the luminous matter? luminous matter kg the rest of the mass is dark matter. how much dark matter does this galaxy contain? dark matter kg

Complete these sentences. if a roller coaster train has a potential energy of 1,500 j and a kinetic energy of 500 j as it starts to travel downhill, its total energy isj. once the roller coaster train gets closer to the bottom of the hill, its kinetic energy increases to 1,100 j, and its potential energy decreases to j. when the train reaches the bottom of the track and is traveling along the ground, its kinetic energy isj.
