THE AGE OF THE UNIVERSE We can calculate the age of the universe given the mean of times for a number of galaxies: . L= Vi where d, - the distance between our Galaxy and a galaxy of \" number \"i \Triangulum Exercises: 1. Making use of the above table and the Hubble law, calculate the velocity of each tabled galaxy, and next, the time of its life. Show calculations, without which any numerical answer/result will be graded as 0. /Velocity should be expressed in km/s, whereas lifetime in years/ Triangulum 2. Plot a graph of \"distance versus velocity\" for the above galaxies. d 2. Plot a graph of \"distance versus velocity\" for the above galaxies. d 3. Determine the age of the universe making use of the formula in the introductory passage (sub- point \"a\"). Subsequently, compare the found result at sub-point \"a\" with the one calculated based on the formula: 77 = I/H, (sub-point \"b\"), where H is the Hubble constant. Show calculations, without which any numerical answer/result will be graded as 0. Calculations: a) b)
