Imagine a photon of light traveling the different paths in the Milky Way described in the following list. Rank the paths based o
n how much time the photon takes to complete each journey, from longest to shortest. A. across the diameter of the galactic halo
B. across the diameter of the galactic disk
C. from the Sun to the center of the galaxy
D. across the diameter of the central bulge
E. through the disk from top to bottom
Longest : A. across the diameter of the galactic halo
B. across the diameter of the galactic disk
D. across the diameter of the central bulge
C. from the Sun to the center of the galaxy
Shortest : E. through the disk from top to bottom
Explanation:
A halo is larger than the diameters of the disk and a disk is larger than diameters of central bulge and the sun being at the center of the universe is in the form of the disk but is outside the bulge.
<u>The disk is small and thinner as compared to its diameters that are about 1000 light-years in thickness and this property makes it flat.</u>

if all glaciers melt, then sea level would increase and then the ocean will over up the whole earth or parts of it, so it is like a big flood all over the earth and it is too high.
Because winds are named from the direction in which they originate, these winds are called prevailing westerlies. Prevailing westerlies in the Northern Hemisphere are responsible for many of the weather movements across the United States and Canada.
