Tips and Walkthrough: Candy Crush Level 7331

For NGC 7331, the radial velocity Vr=820  km  s^-1; if H0=60  km  s^-1 Mpc^-1, find its distance by using Hubble's law, Equation 1.27 . Show that its V-band luminosity LV ≈5 ×10^10 LV, ⊙. Is NGC 7331 more or less luminous than the Milky Way and M 31 ? Show that hR ≈3.6 kpc. What is the disk | Numerade

For a distance d=14 Mpc, find the blue luminosity of NGC 7331 from its apparent total magnitude. Show that ℳ(HI) / LB ≈0.2 in solar units. Assuming the galaxies to have the same B-V color as the Sun, use Table 4.1 to show that M 31 has about the same ℳ(HI) / LB as NGC 7331, and compute this ratio for the Magellanic Clouds. On the basis of Problem 2.8, assume that ℳ / L ≥2 for the stars in NGC 7331 ; show that, even if we include the molecular gas, the mass in its stars is at least five times lar
