Question
Chapter 4, Problem 1MC
To determine
The population of the world in 2050.
Expert Solution & Answer
Answer to Problem 1MC
Option (d) 9.2 billion.
Explanation of Solution
World population data from 1600 to 2100 according to United Nations figure is shown in the Figure 4-1. The graph indicates that there is a huge increase in population from around mid1950, however the rate of increase is slowing down from its peak of 2 percent/year to about half the population of that today.
There are various factors for the decrease in the trend some of them include Infertility rate, turmoil, war, more amount of aged population and less young population is countries like china. In spite of the slowing trend the world population is expected to increase to between 9.2 billion and 11.8 billion in 2050.
Conclusion:
World population from 1600 to 2100 according to United Nations figure is shown in the Figure 4-1 indicates that the number of people in the world is expected to reach 9.2 billion in 2050 years. Therefore, the correct option is (d) 9.2 billion.
The population expected to reach 9.2 billion in 2050. Therefore, option (a) is incorrect.
The population expected to reach 9.2 billion in 2050. Therefore, option (b) is incorrect.
The population expected to reach 9.2 billion in 2050. Therefore, option (c) is incorrect.

Consider a image that is located 30 cm in front of a lens. It forms an upright image 7.5 cm from the lens. Theillumination is so bright that that a faint inverted image, due to reflection off the front of the lens, is observedat 6.0 cm on the incident side of the lens. The lens is then turned around. Then it is observed that the faint,inverted image is now 10 cm on the incident side of the lens.What is the index of refraction of the lens?
2. In class, we discussed several different flow scenarios for which we can make enough
assumptions to simplify the Navier-Stokes equations enough to solve them and obtain
an exact solution. Consulting the cylindrical form of the Navier-Stokes equations copied
