Myron decides to run some errands. While doing so, he drives 1 mile north, four miles east, then one mile south. What is the total distance Myron drove? What is his displacement? (Don't forget that displacement is a vector!)

A6.0-μf air-filled capacitor is connected across a 100-v voltage source. after the source fully charges the capacitor, the capacitor is immersed in transformer oil (of dielectric constant 4.5). how much additional charge flows from the voltage source, which remained connected during the process?
