Draw your own circuit with four resistors (50 Ω, 100 Ω, 120 Ω, ,140 Ω).  Try to make some resistors in parallel with each other, and others in series with each other. Find the equivalent resistance of your circuit. If you want extra practice, attach a 3V battery to your circuit and find the current through each resistor and the electric potential across each resistor.

You manufacture two products, A and B, each of which you sell for $1 profit. Product A requires 5 blobs and 3 globs, and product B requires 3 blobs and 5 globs. Your supplier has 120 blobs and 120 globs available. Use the Excel Solver (or graphical analysis) to answer the following questions. Starting with the original scenario, where A and B each make $1 profit, your supplier has up to 120 blobs and 120 globs available, but you can...

In this assignment, you will be given several different scenarios. You will need to type on a separate sheet of paper which plan type you think would be best for each situation and why you have chosen that plan type. Each scenario will be worth 1 point. There are nine scenarios, so you will receive 1 extra point for turning the assignment in on time. Each scenario will have only one correct answer and you may not use the same...
