Five students from your school who graduated two years ago are in a band. They just cut a CD and began selling it. You love the music and buy a copy. Your two closest friends also love the music and ask you to make copies of the CD for them. Is it ethical for you to copy this CD and give it to other people? Explain your position.

Nick is a programmer. A company hired him to develop software that translates Web sites into French. While doing this, he also figured out how to translate the Web sites into Italian, German, and Russian. Nick claims he owns the extra programs. Do you think programmers own the rights to software programs they create that go beyond what they were hired to do?

To avoid paying sales tax, Jack buys his big purchases online from sellers located outside his state. Jack’s friend’s TV store loses sales because it must charge sales tax. Is it fair that some Internet-based companies are able to avoid charging sales tax when local stores must charge it?

Tina is a candle maker and sells her candles on a Web site. The site also contains photos of famous celebrities and the caption: “These stars would love my candles.” Tina found the photos on the Internet. Is it fair that Tina uses photos of famous people to help sell her products?

A computer hacker, Raoul, broke into computer systems at several businesses for fun. He did not do any damage, but he was caught and put on probation. After a year, he was hired to work at a computer security firm helping to stop hackers.

Does it send the wrong message to computer hackers that they can get good jobs after committing crimes?

You pay $9 to join a music-download service, then$0.45 for each download. Write an algebraic expression for the total amount you spend on x downloads.

In a single-flash geothermal power plant, geothermal water enters the flash chamber (a throttling valve) at $230^{\circ} \mathrm{C}$ as a saturated liquid at a rate of 50 kg/s. The steam resulting from the flashing process enters a turbine and leaves at 20 kPa with a moisture content of 5 percent. Determine the temperature of the steam after the flashing process and the power output from the turbine if the pressure of the steam at the exit of the flash chamber is (a) 1 MPa, (b) 500 kPa, (c) 100 kPa, (d) 50 kPa.

Determine how many times more intense the first sound is compared to the second. train horn: $7.5$ bels soft music: $3.4$ bels

Regarding the hydraulic jack in the previous problem, which ideas were used to analyze the jack? Select all that apply:

a. pressure $=($ force $)$ (area) b. pressure increases linearly with depth in a fluid with a constant density c. the pressure at the bottom of the 4-cm chamber is larger than the pressure at the bottom of the $10-\mathrm{cm}$ chamber d. when a body is stationary, the sum of forces on the body is zero e. when a body is stationary, the sum of moments on the body is zero f. differential pressure $=$ (weight/volume)(change in elevation)

To determine the amount of temporary hearing loss loud music can cause in humans, researchers studied a group of $20$ adult females who were exposed to $110 \mathrm{~dB}$ music for $60$ minutes. Eleven of the $20$ subjects showed a $20.0\mathrm{~dB}$ reduction in hearing sensitivity at $4000 \mathrm{~Hz}$. What is the intensity corresponding to the threshold of hearing for these subjects?

Scuba divers who suffer from decompression sickness are treated in hyperbaric chambers using heliox at pressures up to 120 psi. Calculate the partial pressure of $\mathrm{O}_2$ in a hyperbaric chamber under these conditions.

In May 2006, representatives of the Group of Eight (G8) industrialized nations, including France, Japan, and the U.S., met in Paris and agreed to boost cooperation to fight cybercrime. Participants there confirmed their support of the France-based Council of Europe’s efforts to finalize a Convention on Cybercrime, which will be the first international treaty to deal with the different forms of criminal activity in cyberspace. The treaty would require countries to approve and enforce laws regarding interception of data, interference with computer systems, fraud, and forgery via the Internet. It also requires them to provide national law enforcement with the authority to carry out computer searches and seizures of computer data. “Everyone realizes that we are at a point where business is in transition, technology is in transition, and there is a legal transition as well,” says Randy Picker, a law professor at the University of Chicago. “The reality is, the legal clock is a lot slower than the business or technology clock.”

1. The first international treaty to deal with cybercrime will allow: (A) the G8 to represent the world in technology (B) laws to meet the needs of technology (C) methods to deal with cyberspace crimes (D) ability to search and seize computer data

2. The treaty would require countries to approve and enforce laws regarding: (A) fraud, forgery, interception of computer data, and overuse of the Internet (B) forgery, interception of data, fraud, and computer system interference (C) search and seizures, computer data, fraud, forgery, and cyberspace (D) cybercrime, technology, forgery, fraud, and computer system interference

You are a small business owner who conducts business internationally via the Internet. You are concerned that this may expose your computer system to cybervandalism and cybergerm warfare. To combat this, you wish to upgrade your anti-virus software. Research three brands of anti-virus software, such as Norton and EZAntivirus. Create a chart comparing and contrasting the various features offered by each brand and determine which product best suits your needs. Write a brief report stating your reasons for choosing this software application.
