Answer to Problem 1QQ

The option (b) is the correct answer.

Explanation of Solution

Introduction:

Galaxies can be classified on the basis of shapes and into three main categories: Spiral, Elliptical and Irregular. Spiral galaxies have three main parts: bulge, halo and disk. Bulge is present in center. It contains old stars mostly. The disk contains young stars and forms the arms of the galaxy.

Halo is a loose structure that surrounds the bulge and some parts of disk. The old star clusters or the globular clusters lie in the halo part of the spiral galaxy.It is not the dominant region which is crowded with starsand is called the galactic central region. It is also not like a pancake region. Hence, both options a and c are not right.

Conclusion:

Therefore,a halo of the galaxy is a large, roughly spherical region surrounding the disk.

A cheetah spots a gazelle in the distance and begins to sprint from rest, accelerating uniformly at a rate of 8.00 m/s^2 for 5 seconds. After 5 seconds, the cheetah sees that the gazelle has escaped to safety, so it begins to decelerate uniformly at 6.00 m/s^2 until it comes to a stop.
