(a)
Interpretation:
The weight and cost of Pt and Fe needs to be determined.
Concept Introduction:
Platinum is a precious metal which is also very expensive. These materials are corrosion resistant and are very good conductors of electricity. As a result, the alloys of these metals are often used for electrodes of devices. These electrodes are formed using thin film deposition or screen printing of metal powder dispersions. The substance that gives away the electrodes is said to be oxidized. Platinum is used in automobile catalytic converter for the process of oxidation.
(b)
Interpretation:
The difference in the cost and weight of Pt and Fe needs to be determined.

- Calculate the value for V1, V2 and V3arrow_forwardThis case focuses on data privacy. Information security is essential but usually circumvented. The Cambridge case highlights the potential dangers users experience when unfamiliar with the "terms of service" on social media websites. It shows how they buy and sell user information from popular social media services like Facebook and Instagram. Instructions: Read the attached article. Compose a two-page paper that summarizes the information. State the issue (what happened). What is Cambridge Analytica’s purpose? How does it affect us and our information? Articulate the consequences of “giving” our information away for free. Provide three things you can take away from the article. Provide a thoughtful response.

- Prelab Information Laboratory Preliminary Discussion Second-order RLC Circuit Analysis The second-order RLC circuit shown in figure 1 below represents all voltages and impedances as functions of the complex variable, s. Note, of course, that the impedances associated with R, RL, and Rs are constant independent of frequency, so the 's' notation is omitted. Again, one of the advantages of s-domain analysis is that we can apply all of the circuit analysis techniques learned for AC and DC circuits.

To generate the s-domain expression for the output voltage, Vout(s) = VR(S), for the circuit shown in figure 1, we can apply voltage division in the s-domain as shown in equation 1 below. For equation 1 we define the following circuit parameters.
