Chapter 13, Problem 1RQ
To determine
For what reason can't the advancement of galaxies go from elliptical to spiral? From spiral to elliptical?
Expert Solution & Answer
Explanation of Solution
Galaxies come in three basic classifications, elliptical, spiral, and irregular. Elliptical galaxies are in elliptical shape or round shape, contain no visible gas and dust, and lack hot, bright stars. Spiral galaxies contain spiral arms and a disk. These galaxies contain gas and dust and hot, bright O and B type stars. Finally, irregular galaxies are composed of a chaotic mix of gas and dust, but do not have an obvious central bulge or spiral arms.
The reason that the evolution of galaxies can`t go from elliptical to spiral(or spiral to elliptical) is due to the fact that basic components of these two galaxy types is so different. Elliptical galaxies contain no visible gas and dust, and lack hot, bright stars while spiral galaxies contain gas and dust and hot, bright O and B type stars. So, it`s not possible for one of these types of galaxies to evolve to become the other type, whose constituents are very different.

The distance of the fall is several meters, and the calculation shows a high probability of injury to the cowboy from the stunt. Let's look at a simpler situation. Suppose the director asks you to have the cowboy step off a platform 2.55 m off the ground and land on his feet on the ground. The cowboy keeps his legs straight as he falls, but then bends at the knees as soon as he touches the ground. This allows the center of mass of his body to move through a distance of 0.660 m before his body comes to rest. (Center of mass will be formally defined in Linear Momentum and Collisions.) You assume this motion to be under constant acceleration of the center of mass of his body. To assess the degree of danger to the cowboy in this stunt, you wish to calculate the average force upward on his body from the ground, as a multiple of the cowboy's…arrow_forward
