Name: Section: SP1L-17 Date: 2/26/11 Coulomb’s Law: What is the charge on a charged pith ball? Experimental Determination of the Electrostatic Force acting between two charged pith balls Equipment: a pvc pipe and fur or wool‚ a metric ruler‚ a protractor‚ two pith balls on a stand as in figure 1. Your teacher will tell you the mass of your pith balls. Procedure: Make sure the strings of your two pith balls are untangled as in figure 1. Make sure that the pith balls are neutral by rubbing

Name: Aaron Banks Section: Thursday PRELAB: A MODEL FOR CIRCUITS I: ELECTRIC CURRENT 1. What do you predict for the rankings of the brightness of bulbs A‚ B‚ and C in Figure 2-1? A>B>C A being the brightest 2. How do you predict that changing the direction of the current by reversing the connections to the battery in Figure 2-1 would change the rankings in (1)? I don’t think it will change at all. The brightness should be the same in diagram b and diagram a it should also stay

Jennifer Nelson Unit 3 Assignment 1 Date due: July 12 Date submitted: July 12 Define Key Terms Electrical circuit: A complete loop of material that conducts electricity. Frequency: When describing energy that acts like waves‚ the number of times that the entire waveform repeats per second. Amplitude: When describing energy that acts like waves‚ when graphing the waveform centered on the X axis‚ and graphing some kind of power (for example‚ voltage) on the Y axis‚ the amplitude is the maximum

Assignment Week 4 Chapter 11 20. A parallel RL circuit has values of IL = 240 mA and IR = 180 mA. Calculate the magnitude and phase angle of the circuit current. It=√ IL^2 + IR^2= √ 240mA^2 + 180mA^2= 0.3 x 10^-3= 300mA θ= tan^-1(-IL/IR)= (-240mA/180mA)= -53° 300mA∟-53° 22. Calculate the total impedance for the circuit shown in Figure 11.38b. It= √IL^2 + IR^2= √800mA^2 + 120mA^2= 0.808949 x 10^-3= 808.95mA Zt= Vs/It= 120V/808.95mA = 148Ω θ= tan^-1(-IL/IR)= (-800mA/120mA)= -81.5= 82° 148∟82° 24

ANSWERS TO CASE DISCUSSION QUESTIONS 1. What does the Chevy Volt case tell you about the nature of strategic decision making at a large complex organization like General Motors? Strategic decision making is often met with cognitive biases that are formed around prior victories or defeats. 2. What trends in the external environment favored the pursuit of the Chevy Volt project? Trends included increases in oil prices‚ global warming‚ costs of manufacturing lithium ion batteries was falling

1. What does the Chevy Volt case tell you about the nature of strategic decision making at a large complex organization like GM? From the Chevy Volt case‚ it showed that decision making in a large complex organization isn’t easy. There’re many processes and accessories. Making decision in a huge organization could not be done by Top managements or some departments. They have to discuss in a meeting and ask for the comments from all accessories. So they need the same mind set and objectives for
