1. (10 pts). Do the posted “Power Cord” problem. Use the Essay Template format and give the answers to all five questions on one page. Be brief and concise. On a separate page show the supporting calculations you did to find the answers to questions 4 and 5. (Hint: In these calculations do not make too crude approximations; the numbers you are asked to compare in the end differ only very slightly, so you should use sufficient decimal places to show how big – or small – that difference actually is.

2. (10 pts = 1 + 1 + 4×2).  Answer the posted “Frequencies & Wavelengths” questions.
