2 pts Set all the sliders to O. In the 2nd graph, click on the dropdown and choose the observed rotation curve of the Milky Way. Your job is to change the amount of dark matter around (in the top graph) at different radii, until you match the Milky Way's rotation curve as best you can. Do that. Make sure the center of the red dots match the rotation curve line. The Earth is situated at about 25 thousand light-years from the center of the Milky Way. What is the dark matter density all around you in units of kilograms per Earth volume (i.e. what is the mass of dark matter enclosed in a space the size of the Earth? You can read the value in green above the correct slider to get the exact value on the y- axis. Since the y axis is in a log scale, it means you have to take that number and raise 10 to the power of that number to get the actual value, i.e. 10^(number on y scale) to get the answer in kg/Earth_ Volume. Enter just the number of kg/Earth_volume in the field below. No units need to be inputted.D Question 2 2 pts At what radius in the luminous disk of the Milky Way Galaxy is the density of dark matter the lowest?
