3. Make sure you show your work, or give an explanation of how you came to your answer. If there is no work or explanation there will be NO POINTS. 1. A force with magnitude F is needed to separate two charges by a distance r. What will be 1 the new force F ′ , needed to keep the two charges separated by a distance 2 r?
As a reverse DC voltage is applied across the diode, its capacitance varies. The higher the voltage, the less the capacitance. This is due to depletion layers of the diode junction, but we wont get into details here. This variable capacitor in conjunction with the stub, which is actually an inductor (coil) is the basis of our voltage controlled oscillator! As the voltage increases across D5, the frequency of oscillation increases.
Calculate the impedance by the measured values of voltage and current from the oscilloscope. Also calculate the impedance from = − C. Answer: Impedance, Z = 5∠0 34.65 60.48°) = 173.25 - 60.48⁰ = 85.37 Ω - j150.76 Ω Again, XC = 1/ = 1/ (6280 x 10-6) = 159.24
Clearly indicate which moral standard, framework, or case you are utilizing. 3. Don’t invent facts to make the issues raised in the case easier. 4. Please also utilize only materials from the course in writing your answers.
| x 1 (33.33%) | Student work demonstrates no understanding or progress towards achievement of this outcome. | The student does not attempt to describe the difference between legisation and case law or indicates confusion as to the concepts of legislation and case law. | The student attempts to describe the difference between legislation and case law, but is not successful. | The student is able to accurately describe the difference in legislation and case law based only on the source. | The student is able to accurately describe the differences between legislation and case law, including the source and either 1) the weight of the authority or 2) how it can be amended or changed.
Exercise 4.1.2: The voltage for registering a bit of 1 on Ethernet can be as low as 2.5 volts or even 1 volt. Why is this so low when the capacity for transmitting electricity on the copper wire is so high? Use your textbook and Internet research to support your answer. Because the voltage used to transmit data needs only be high enough for the receiver to detect it. Making the voltage higher would make the receiver electronics more difficult.
A reporting entity may begin the second statement with net income. Although Zumiez states the total amount of comprehensive income, they fail to break out the components of their total anywhere in their financial statements. SFAS No. 130 requires the disclosure of comprehensive income and discusses how to report and disclose comprehensive income and its components, including net income. However, it does not specify when to recognize or how to measure the items that make up comprehensive income.
-Exothermic is energy needed to break the bonds is less than the energy released and endothermic is the energy needed to break the bonds is greater than the energy released. 3. Read the entire laboratory activity. Form a hypothesis about how to distinguish exothermic and endothermic processes. Record your hypothesis on page 123.
Teachers may give generic, informal feedback while the work is being completed but may not indicate what candidates need to do to improve their work. Candidates should not be given the opportunity to redraft their work, as this is likely to require an input of specific advice. Candidates should be made aware of the time allowed for carrying out this part of the task. Candidates' access to resources is determined by those available to the centre and/or to candidates at home. The research information should be brought into the classroom.
Mini-Lab 6-06: Foiled for the Last Time! Purpose: What if you expect something to happen, but it doesn’t? This is an exercise in thinking “outside the box”. Think about this: When there is a positive potential difference between two substances, the reaction will be spontaneous. Reduction Reaction | Reduction Potential | Cu2+ + 2e- Cu(s) | 0.34 V | Al3+ + 3e- Al(s) | -1.66 V | Safety 1) Don’t eat or drink anything in the lab.
