A Van de Graaff generator is one of the original particle accelerators and can be used to accelerate charged particles like protons or electrons. You may have seen it used to make human hair stand on end or produce large sparks. One application of the Van de Graaff generator is to create X-rays by bombarding a hard metal target with the beam. Consider a beam of protons at 1.00 keV and a current of 5.00 mA produced by the generator. (a) What is the speed of the protons? (b) How many protons are produced each second?

Let’s stop ignoring the greenhouse effect and incorporate it into the previous problem in a very rough way. Assume the atmosphere is a single layer, a spherical shell around Earth, with an emissivity e = 0.77 (chosen simply to give the right answer) at infrared wavelengths emitted by Earth and by the atmosphere. However, the atmosphere is transparent to the Sun’s radiation (that is, assume the radiation is at visible wavelengths with no infrared), so the Sun’s radiation reaches the surface. The greenhouse effect comes from the difference between the atmosphere’s transmission of visible light and its rather strong absorption of infrared. Note that the atmosphere’s radius is not significantly different from Earth’s, but since the atmosphere is a layer above Earth, it emits radiation both upward and downward, so it has twice Earth’s area. There are three radiative energy transfers in this problem: solar radiation absorbed by Earth’s surface; infrared radiation from the surface, which is absorbed by the atmosphere according to its emissivity; and infrared radiation from the atmosphere, half of which is absorbed by Earth and half of which goes out into space. Apply the method of the previous problem to get an equation for Earth’s surface and one for the atmosphere, and solve them for the two unknown temperatures, surface and atmosphere.    A. In terms of Earth’s radius, the constant σσ, and the unknown temperature TsTs of the surface, what is the power of the infrared radiation from the surface?   B. What is the power of Earth’s radiation absorbed by the atmosphere?   C. In terms of the unknown temperature TeTe of the atmosphere, what is the power radiated from the atmosphere?   D. Write an equation that says the power of the radiation the atmosphere absorbs from Earth equals the power of the radiation it emits.   E. Half of the power radiated by the atmosphere hits Earth. Write an equation that says that the power Earth absorbs from the atmosphere and the Sun equals the power that it emits.   F. Solve your two equations for the unknown temperature of Earth.

In car racing, one advantage of mixing liquid nitrous oxide (\text{N}_{2}\text{O}) with air is that the boiling of the “nitrous” absorbs latent heat of vaporization and thus cools the air and ultimately the fuel-air mixture, allowing more fuel-air mixture to go into each cylinder. As a very rough look at this process, suppose 1.0 mol of nitrous oxide gas at its boiling point, -88\ \text{°C} , is mixed with 4.0 mol of air (assumed diatomic) at 30\ \text{°C} . What is the final temperature of the mixture? Use the measured heat capacity of \text{N}_{2}\text{O} at 25\ \text{°C} , which is 30.4\ \text{J/mol}\ \text{°C} . (The primary advantage of nitrous oxide is that it consists of 1/3 oxygen, which is more than air contains, so it supplies more oxygen to burn the fuel. Another advantage is that its decomposition into nitrogen and oxygen releases energy in the cylinder.)

In Germany it takes three workers to make one television and four workers to make one video camera. In Poland it takes six workers to make one television and 12 workers to make one video camera.    A. Who has the absolute advantage in the production of televisions? Who has the absolute advantage in the production of video cameras? How can you tell?   B. Calculate the opportunity cost of producing one additional television set in Germany and in Poland. (Your calculation may involve fractions, which is fine.) Which country has a comparative advantage in the production of televisions?   C. Calculate the opportunity cost of producing one video camera in Germany and in Poland. Which country has a comparative advantage in the production of video cameras?   D. In this example, is absolute advantage the same as comparative advantage, or not?   E. In what product should Germany specialize? In what product should Poland specialize?

Do [Exercise 3.16](3-problems-exercises#eip-287) again using analytical techniques and change the second leg of the walk to \text{25.0 m} straight south. (This is equivalent to subtracting \mathbf{B} from \mathbf{A} —that is, finding \textbf{R}\prime = \textbf{A – B} ) (b) Repeat again, but now you first walk \text{25}\text{.}\text{0 m} north and then \text{18}\text{.}\text{0 m} east. (This is equivalent to subtract \mathbf{A} from \mathbf{B} —that is, to find \mathbf{A} = {\mathbf{B} + \mathbf{C}} . Is that consistent with your result?)
