Question: The purpose of this problem is to show the entire concept of dimensional consistency can be summarized by the old saying “You can’t add apples and oranges.” If you have studied power series expansions in a calculus course, you know the standard mathematical functions such as trigonometric functions, logarithms, and exponential functions can be expressed as infinite sums of the form {\sum\limits_{n = 0}^{\infty}{a_{n}x^{n}}} = a_{0} + a_{1}x + a_{2}x^{2} + a_{3}x^{3} + \cdots, where the a_{n} are dimensionless constants for all n = 0,1,2,\cdots and _x_ is the argument of the function. (If you have not studied power series in calculus yet, just trust us.) Use this fact to explain why the requirement that all terms in an equation have the same dimensions is sufficient as a definition of dimensional consistency. That is, it actually implies the arguments of standard mathematical functions must be dimensionless, so it is not really necessary to make this latter condition a separate requirement of the definition of dimensional consistency as we have done in this section.

Question: 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?

Question: Is it OK for companies to profile customers and predict their purchase behavior? Every time you, as a consumer, visit a website, your “cookies” are gathered and used to better understand your shopping behavior. Several years ago, Target’s analysts developed an algorithm based upon Target customer buying behavior that predicted pregnancy. Those predicted to be pregnant—based upon the products they bought—were sent targeted marketing materials. The angry father of a high school student accused Target of erroneously sending his daughter a sales flyer for baby products. Supposedly, the daughter was pregnant.Read more about the incident.How do you feel about companies gathering intimate details about you for marketing purposes? Do you believe these companies develop a better relationship with you as a result? Despite being accurate, was Target’s pregnancy-predicting algorithm ethical, invasive, or somewhere in between?
