Q.5 Identify the names of the four major arms of Milky way galaxy : a) Norma and Cygnus, Sagittarius, Scutum-crux, Perseus. b) Norma and Cygnus, Orion, Scrotum-crock, Perseus. c) Norma and Clittorus, Sagittarius, Scrotum-crux, Perseus. d) Norma and Cygnus, Orion , Scutum-crux, Perseus. Q.6 In a far far away Galaxy lies a solar system untold, wherein, lies the planet, Stephenland inhabited by Meeseeks (a simple, but sentient species ). Their planet is invaded by the dreaded Brainiac Titanoids and their minions, P'nados . They started exploiting the natural resources of the planet at a scale, wherein, it actually started having affecting the mass of the planet. The mass lost was so huge that the atmosphere of the planet was actually endangered. They're now facing the threat of a waning atmosphere due to the decrease in Stephenland's gravity. Consider the final situation to be when the critical mass is reached and the planet starts losing its atmosphere and hence, Everyone DiesTM. Assume the ratio of the initial mass and the mass at the onset of the destruction of the planet to be 125/64, assuming that the mass lost is uniformly distributed through the planet and the shape is spherical, the density of the planet is constant throughout the whole process. a) The ratio of the initial and final escape velocities of air on the surface 5/4. b) The ratio of the initial and final surface temperatures is 25/16. c) The ratio of the initial and final surface temperatures is 16/25. d) The ratio of the initial and final escape velocities of air on the surface 4/5.

Figure 2 shows the "rotation curve" of NGC 2742. It plots the “radial velocity (V)" (how fast material is moving either toward or away from us) that is measured for objects at different distances (R = radius") from the center of the galaxy. The center of the galaxy is at 0 kpc (kiloparsecs) with a speed of 9 km/sec away from us. (These velocities have been corrected for the observed tilt of the galaxy and represent true orbital velocities of the stars and gas.) 200 100 U4779 -100 As you can see, one side of the galaxy is moving with a negative velocity (spinning toward us), while the other side has a positive velocity (spinning away from us). Using Newton's gravity equation, we will be able to determine the gravitational mass of the entire galaxy and how the mass varies versus distance from the galaxy's center. -200 -8 8 -4 Radius (kpc) Read the following text carefully and follow the instructions: Select five radii spaced evenly from 0-10 kpc across the galaxy.
