The population of India was 435 million in 1960(t=0) and 487 million in 1965(t=5). The projected population for 2050 is $1.57$ billion. Use the solution of the logistic equation and the 2050 projected population to determine the carrying capacity.

The figure shows current population with a forecast of population for 2050 for the six most populated countries of the world. Use the data to answer the question below.

Population with a Forecast

China was the most populous country in the world in 2000. What country is forecast to be the most populous by 2050? What is the difference between the forecast population of this country and China in 2050?

The United States spends more money on health care than any other country. To gauge how fast costs are rising we recorded the total health care costs since 1950.

In the following, name the term defined or answer the question.

The level of capacity for which a process was designed and at which it operates at minimum cost.

_______________The scientific study of human populations is called demography

Explain how the distribution and availability of resources might influence population density?

The earth is approximately spherical, with a diameter of $1.27 \times 10^{7}$ m. It takes 24.0 hours for the earth to complete one revolution. What are the tangential speed and radial acceleration of a point on the surface of the earth, at the equator?

The Earth can be thought of as a spherical capacitor. If the net charge on the Earth is $-7.8 \cdot 10^5 \mathrm{C}$, find (a) the capacitance of the Earth and (b) the electric potential energy stored on the Earth's surface.

Name the process that includes the movement of magma onto Earth's surface.

Why doesn't the method of spherical means work for two-dimensional waves?

Does Webmail use POP3, IMAP, or neither? If one of these, why was that one chosen? If neither, which one is it closer to in spirit?

Assume that the RTT between a client and the local DNS server is TT$_l$, while the RTT between the local DNS server and other DNS servers is RTT$_r$ . Assume that no DNS server performs caching. a. What is the total response time for the scenario illustrated in Figure? b. What is the total response time for the scenario illustrated in Figure? c. Assume now that the DNS record for the requested name is cached at the local DNS server. What is the total response time for the two scenarios?
