Name: ____________________ Section: ___________________ Capacitance in a Circuit Part 1: DATA TABLE: Time (seconds) Voltage (V) Questions: Was the voltage across the LED the same as the battery voltage? Why or why not? How long did it take the voltage across the capacitor to rise to the circuit voltage? Was it instantaneous? What happened to the voltage when you removed the capacitor from the circuit? How did the capacitor become discharged? Part 2: Questions: A. Did the LED light up? Why or why not? B. What did the ammeter show when you first closed the circuit? C. What did the ammeter show after a few seconds? D. How do you explain your observations? Part 3: Questions: A. What did the voltage across the capacitor do when you first closed the circuit? B. Was the voltage across the capacitor the same as the voltage of the battery? C. What did the voltage across the capacitor do when you disconnected the battery?
Name: ____________________ Section: ___________________ Reflection and Refraction Part 1 - Reflection DATA TABLE: Incident angle, ?i 30 45 60 Reflected angle, ?r What can you conclude about the relationship of ?i and ?r? Does this verify the law of reflection? Part 2 - Reflection: Step I - Find the image location, circle that point and label it “I”. Measure and record the object distance do and the image distance di. What can you say about the location of the image? Step J - Is the image real or virtual? Part 3 - Refraction and the Refractive Index of Water: Data Table Experiment Incident angle, ?i Refracted angle, ?r Index of refraction, n 1 2 3 Average value of the index of refraction, navg = _______________________. Find the percent difference between the known value and your average experimental value. Part 4 - Refraction and Refractive Index: Data Table Experiment Incident angle, ?i Refracted angle, ?r Index of refraction, n 1 2 3 Average value of the index of refraction, navg = _______________________. Find the percent difference between the known value of 1.49 and your average experimental value.
Consider the 604 N weight held by two cables shown below. The left-hand cable had tension T2 and makes an angle of 44 degrees with the ceiling. The right hand cable had tension T1 and makes an angle of 45 degrees with the ceiling.
A plane triatomic molecule consists of equal masses m at the vertices of a triangle. If the masses were at rest, the masses would be on an equilateral triangle of side b. The molecule is held together by forces that are harmonic for small oscillations & the force constants are each equal to k. Consider motion in the plane of the molecule only. Write expressions for the kinetic energy, the potential energy, & the Lagrangian of the system. Derive the equations of motion using Lagrange’s equations. Assume small oscillations. Set up & solve the solve the secular equation for the normal mode eigenfrequencies & eigenvectors. How many normal modes are there? Do any of them correspond to ? = 0? Answer the following question using mostly WORDS, in complete, grammatically correct English sentences! You may also make a sketch if that helps your discussion. Qualitatively discuss the motion of the 3 masses in each of the normal modes.
As you will recall, the concept of Ren, or humanness, is the most important principle in Confucian ethics. This is the idea of treating others with compassion. Ren frames all other virtues (both moral and non-moral). For this assignment, demonstrate your understanding of Ren and other key concepts of Confucian ethics by choosing one of the following options: Write a Poem Write lyrics and/or record a Song (may be an original tune or a parody) Write a script and/or record a TV or Radio Commercial Create a PowerPoint Presentation Create a Movie Poster Create a Travel Brochure While you may choose any of the above formats, you must cover some of the basics surrounding Ren. Include a definition of it, examples of Ren in everyday life, why Ren is an important tenet in Confucian ethics, and how does one show Ren towards others? What you submit to the drop box below will vary depending on which form of expression you choose above. However, it is your responsibility to ensure that what you submit can be easily viewed by an average person using a computer equipped with Internet access and Microsoft Office. Some examples might include: Poem: would likely take the form of a Microsoft Word document. Song: lyrics would likely be done in a Word document. Song: audio recording would ideally be in an MP3 format (to ensure that the file is small enough to submit). TV/Radio Commercial: script would likely be done in a Word document. TV Commercial: video would likely be uploaded to YouTube (or similar) and hyperlink provided in the dropbox. Radio Commercial: audio recording would ideally be in an MP3 format (to ensure that the file is small enough to submit).
