Pretend the graph you see below is a galaxy spectrum obtained from the Hubble's Law Lab. Use it to calculate the average recession velocity of this galaxy. (Note that 1 nm = 10 Angstroms) Spectrum of a galaxy in the Coma cluster 140 120 100 80 Intensity of light (arbitrary scale) 60 40 20 380 400 420 440 460 480 500 Observed wavelength (nm) O 8,000 km/s O 14,500 km/s O 290,000 km/s 11,200 km/sAssume the galaxy pictured above has an apparent magnitude of 13.4. What is the distance to this galaxy, in Mpc (use the same assumptions you did in the lab)? 120 Mpc O 35.4 Mpc O 80.2 Mpc O 55.6 MpcUsing one of your graph papers, made a Hubble Plot like you did in the Hubble's Law lab. Include both the galaxy from the previous two questions, and also the following galaxies: #2: A galaxy with recession velocity of 14,500 km/s and a distance of 240 Mpc #3: A galaxy with recession velocity of 7,000 km/s and a distance of 100 Mpc #4: A galaxy with a recession velocity of 4,500 km/s and a distance of 50 Mpc #5: A galaxy with a recession velocity of 2,000 km/s and a distance of 40 Mpc On your graph, plot the best t line and use it to calculate a value for Hubble's constant. Enter in your value for Hubble's constant below (in km/s/Mpc). You will not actually upload this graph (although in the rst two questions you may have been asked to upload your graph from when you originally did Lab 12), you are just using it to determine H0. Now, using your result from the previous question, determine the age of the universe, in years
