Is Technology Our Savior - Or Our Slayer? Click the title to view the video. You will also have access to a transcript of the talk. Essay One/Assignment One Answer the following questions regarding the video above. Each response should fully address the question. Use specific examples in your responses. 1. What is the speaker's thesis? is it stated in specific term or is the thesis vague? What is your initial reaction to the thesis? Do you feel as if you agree or disagree with the speaker at this stage? 2. It is helpful to establish the limits of your argument and what you are trying to accomplish through a concession statement. What is the speaker's concession statement? What are the limits of the argument? 3. You should let your reader know your bias, but do not let that bias blind you to the primary components of good argumentation: sound. thoughtful evidence and respectfully and reasonably addressing opposing ideas. What are the speaker's biases? How are those biases addressed: 4. facts are statements that can be proven using objective data. List three facts presented by the speaker. 5. Opinions are personal views, or judgments, that cannot be proven. List three opinions presented by the speaker. 6. To persuade a skeptical audience, you will need to use a wide range of evidence. Scientific studies, opinions from experts, historical precedent, statistics, personal anecdotes, and current events are all types of evidence that you might use in explaining your point. Discuss the evidence used by the speaker. 7. It is essential that you not only address counterarguments but also do so respectfully. What opposition statements does the speaker address? what way are those statements addressed? 8. Make sure that your word choice and writing style is appropriate for both your subject and your audience. Describe the speaker's tone as well as its effectiveness. 9. In this TedTalk, the speaker touches on a number of issues that can be further developed into arguments of their own. List 4-5 topics that the speaker mentions that would be good topics for an argumentative essay. Don't respond to the speaker's thesis, as you will not be arguing for or against their stand. Consider 4-5 topics that the speaker mentions and that you would be interested in researching.
24. A point charge q1=2.40 μC is held stationary at the origin. A second point charge q2= -4.30 μC moves from the point x=0.150 m, y=0 to the point x=0.250 m, y= 0.250 m. How much work is done by the electric force on q2? 25. A charge of 28.0 nC is placed in a uniform electric field that is directed vertically upward and has a magnitude of 4.00 x 10^4 V/m. What work is done by the electric force when the charge moves (a) 0.450 m to the right; (b) 0.670 m upward; (c) 2.60 m at an angle of 45.0° downward from the horizontal? 26. A small particle has charge -5.00 μC and mass 2.00 x 10^-4 kg. It moves from point A, where the electric potential is VA=+200 V, to point B, where the electric potential is VB =+800 V. The electric force is the only force acting on the particle. The particle has speed 5.00 m/s at point A. What is its speed at point B? Is it moving faster or slower at B than at A? Explain. 27. A uniform electric field has magnitude E and is directed in the negative x-direction. The potential difference between point a (at x=0.60 m) and point b (at x=0.90 m) is 240 V. (a) Which point, a or b, is at the higher potential? (b) Calculate the value of E. (c) A negative point charge q=-0.200 μC is moved from b to a. Calculate the work done on the point charge by the electric field. 28. A silver wire 2.6 mm in diameter transfers a charge of 420 C in 80 min. Silver contains 5.8 x 10^28 free electrons per cubic meter. (a) What is the current in the wire? (b) What is the magnitude of the drift velocity of the electrons in the wire? 29. When switch S in the diagram is open, the voltmeter V of the battery reads 3.08 V. When the switch is closed, the voltmeter reading drops to 2.97 V, and the ammeter A reads 1.65 A. Find the emf, the internal resistance of the battery, and the circuit resistance R. 31. In the circuit shown in the diagram, find (a) the rate of conversion of internal (chemical) energy to electrical energy within the battery; (b) the rate of dissipation of electrical energy in the battery; (c) the rate of dissipation of electrical energy in the external resistor.
