Final_Exam

toc Your final exam will be taken in two parts: Completing your Essays with satisfactory answers guarantees that you will receive a passing grade. Beyond that, Multiple Choice results will determine HOW WELL you pass. These cut-offs will be in the spirit of 1-5 Quality Points, rather than 0-100%.
 * Benchmark-like Essays (which determine whether you pass or fail);
 * Multiple Choice Questions (which determine your letter grade).



Benchmark Essays
You will have four essays, randomly assigned, one from each of the following four categories:

Nature:

 * [[image:Finals_Nature.png link="Finals_Nature1"]] || Natural resources are often found in a form that requires chemical and/or physical changes. Choose some examples and discuss them in a way that illustrates the meaning of chemical and physical changes, and the difference between them. ||
 * [[image:Finals_Nature.png link="Finals_Nature2"]] || What is crude oil, and how do we process it to make it useful? ||
 * [[image:Finals_Nature.png link="Finals_Nature3"]] || What is fire? What happens to the fuel as it burns? ||

Motion:

 * [[image:Finals_Motion.png link="Finals_Motion1"]] || Archimedes famously said, "Give me a lever long enough and a fulcrum on which to place it, and I shall move the world." Give an example of leverage in action, and explain how this related to the concept of mechanical advantage. ||
 * [[image:Finals_Motion.png link="Finals_Motion2"]] || Suppose you had two simple machines and you knew that one had twice the mechanical advantage of the other. How could you tell which was which, and how would that influence your use of the two tools? Can you give examples of common tools that display a variety of mechanical advantages? ||
 * [[image:Finals_Motion.png link="Finals_Motion3"]] || Explain how Newton's Laws of Motion would apply in a microgravity space hotel. ||
 * [[image:Finals_Motion.png link="Finals_Motion4"]] || Explain how astronomers track asteroids. What paths do they take, and how can we anticipate possible impacts with the Earth? ||

Electricity:

 * [[image:Finals_Electricity.png link="Finals_Electricity1"]] || Suppose you had a city that needed 40 units of power, with an environmental impact less than 40. The power company has narrowed the choices down to Trash-To-Steam facilities (power=5, cost=30, impact=6 for each unit), Wind facilities (power=2, cost=10, impact=1 per unit), and Hydroelectric facilities (power=20, cost=160, impact=10 per unit). Please make a recommendation and justify it! How could future developments change the numbers given in this scenario? ||
 * [[image:Finals_Electricity.png link="Finals_Electricity2"]] || What is the difference between power and energy? What does the electrical utility actually charge you for? ||
 * [[image:Finals_Electricity.png link="Finals_Electricity3"]] || What is the purpose of a fuse or a circuit breaker? ||
 * [[image:Finals_Electricity.png link="Finals_Electricity4"]] || Give an example which shows how electrical switches/sensors can be used to process complex information. ||

Information:

 * [[image:Finals_Information.png link="Finals_Information1"]] || How do color monitors and color printers "take shortcuts" in producing a full-color image? ||
 * [[image:Finals_Information.png link="Finals_Information2"]] || AM and FM radio often have different programming, but they differ in more important ways. Discuss the amplitude and frequency of radio stations on both parts of the dial. ||
 * [[image:Finals_Information.png link="Finals_Information3"]] || Different parts of the electromagnetic spectrum are used to transmit information. Choose two parts of the spectrum in common use, and explain the qualities that make them good for transmitting information. ||
