- How do we know andromeda galaxy is moving towards us?arrow_forwardOur Solar System is about 8.3 kpc from the centre of our galaxy. Using Newton's Universal Gravitation Law and Kepler's Third Law, calculate the approximate mass of our Milky Way if we know that the orbital velocity of the Sun around the centre of the galaxy is 225 km/s. (Hint: Use the formula for orbital velocity: v = GM -and problem , r -11 m3 Note: G is the Universal Gravitation Constant, G 6.67 × 10 kg s2' 1 kpс 1000 рс аnd 1 рс 3.1 x 1016 m. Also, pay attention to units!!! – i.e. orbital m3 velocity is in km/s and the universal gravitation constant is in kgs2 а) 8.7 х 1035 b) 2.0 x 1041kg c) 2.0 × 1030 d) 6.0 × 1024 kg kg kgarrow_forwardThe Tully-Fischer method relies on being able to relate the mass of a galaxy to its rotation velocity. Stars in the outer-most regions of the Milky Way galaxy, located at a distance of 50 kpc from the galactic centre, are observed to orbit at a speed vrot = 250 km s−1. Using Kepler’s 3rd Law, determine the mass in the Milky Way that lies interior to 50 kpc. Express your answer in units of the Solar mass.arrow_forward
- If the active core of a galaxy contains a black hole of 106 M, what will the orbital period be for matter orbiting the black hole at a distance of 0.42 AU? Hint: Use the formula for circular velocityarrow_forwardShow that: how this come about, and also include the interpretation of how you got therearrow_forwardState And Explain Hubbles Law?arrow_forward
- Explain the Higher-Order Systems?arrow_forwardThe Sun is moving at 220 ??/? around the Galactic Center at a more-or-less constant distance of 8.5 ???. To appreciate how remarkable this is, consider the following questions: a) How massive would the Sun have to be for the Earth to have an orbital velocity of 220 km/s at 1 AU? b) How fast would the Earth move if it was in orbit around the Sun at a distance of 8.5 kpc? Of course, you may ignore the effects of all other stars in this calculation.arrow_forwardThe best evidence for a black hole at the center of the Galaxy also comes from the application of Kepler’s third law. Suppose a star at a distance of 20 light-hours from the center of the Galaxy has an orbital speed of 6200 km/s. How much mass must be located inside its orbit?arrow_forward
