When a new employee is placed with an employer, a record is created that identifies the employment relationship. The firm follows up on job placements by surveying employers and employees and enters the results into the AIS. Employees are uniquely identified by social security number. In records that contain client survey data, social security number is likely: ? a. Absent. ? b. The primary key. ? c. Combined with other data fields to form a primary key. ? d. A foreign key.

You're at a restaurant and your dining companion is getting really annoyed with you because you keep complaining about the impacts of land use extensification on natural ecosystems. You need a good scientific rationale for why you want to choose a type of food that will have the least impact on land use extensification. Which of the following is the best explanation? A. I'm avoiding eating most meat because the loss of caloric (food) energy in animals means that more land is needed to support meat production than is needed to support the production of fruits and vegetables. B. I'm avoiding any items on the menu that could have come from sub-Saharan Africa because this is where the most land use extensification occurs. C. I'm avoiding eating any food that is green because it contains chlorophyll; when chlorophyll is removed from an ecosystem, it takes food away from the animals that depend on it. D. I'm avoiding eating meat because lots of forest in Indonesia and Africa is cleared to make room for cattle grazing.

3) Low Pass Filter [diagram omitted] a) What is Vout for very low and very high frequencies? b) Derive an expression for the angular frequency ? at which the impedance of the capacitor |Zc| is equal to R. c) Using the voltage divider formula derive an expression for the ratio of Vout to Vin, put it in the form shown below. This is what is known as the transfer function of this circuit and it describes as a function of frequency how the amplitudes of sine waves at different frequencies are transferred from the input to the output. Vout/Vin = 1 / (1 + ?) d) What is the value of this ratio at the angular frequency found in part b? This special frequency is known as the cut-off frequency for the filter. Below this frequency the output stays fairly constant, above this frequency it drops like 1/?. We usually say that this frequency corresponds to the bandwidth of the low pass filter. A note for those who know more or are going on: the magnitude of this ratio is wrong here because we used the absolute value for the impedance of the capacitor; if you use the actual complex impedance you get a different numerical value, but conceptually this simplified case can help to understand what is going on.
