A potential difference of 25.0 V is applied between the ends of a 30.0-m gold wire with a diameter of 5.50 mm. The resistivity of the wire is 2.44 × 10−8 Ω.m., Calculate
the drift speed of the electron in the wire. Assume one atom conducts one electron.

(molar mass of gold =196.97 g/mol and ρgold = 19.32 g/cm3

Imagine you work as a consultant, and your daily job involves listening to the constructive criticism of others. as part of your job, you must listen to opposing viewpoints to make important decisions. in this activity, you are a consulting dam engineer. you must make a decision about four different dams; should they be repaired, taken down, or left alone? you will listen to contrasting opinions about what should be done with the dams before you make the final decision. as the consulting dam engineer, what do you decide to do with this dam? explain your reasoning. by making your decision, did you support the opinions of the mayor and/or the dam safety official? why or why not?

The experiment was repeated many years later but the gases were mixed in a different type of container. a white solid was obtained which was xenon fluoride. predict whether you think 1) krypton and 2) radon will react with fluorine. explain reasons for your predictions
