At last you are in a place where the heat and high density are no longer bothering you. However, although the density is very low, the gas around you is extremely high in temperature
In fact, the temperature is so high that it is emitting lots of X-rays, which are creating cancer-causing mutations in your body at a rapid rate. Well, at least the view is great! There are no stars anywhere within about 10,000 light-years of you, but at slightly greater distances your sky is brightened by many beautiful, star-filled structures, some with majestic spiral shapes. Where are you? A) You are in the universe when it was about 200 million years old, just before galaxies began forming.
B) You are in the center of the Milky Way Galaxy, looking outward into the Local Group.
C) You are somewhere between the Andromeda and Milky Way galaxies in the Local Group.
D) You are in intergalactic space within a rich cluster of thousands of galaxies.
E) You are in the outskirts of a galaxy whose nucleus is a powerful quasar.

In the circuit shown in Figure OQ28.12, each battery is delivering energy to the circuit by electrical transmission. All the resistors have equal resistance. Rank the magnitudes of the currents at the same points from greatest to least, noting any cases of equality
1. b > c > a = e > d 2. a > d > b = c > e 3. e > a = b > c = d 4. c = d > b > a > e
