Consider an electrophysiology experiment in which a 0.200 ~mm0.200 mm diameter round silver wire is used as a stimulation electrode. In this experiment, a current of 4.69~ mA4.69 mA is applied through the wire. The density of free electrons in silver is 5.86 \times 10^{28}~ \frac{\text{electrons}}{m^3}5.86×10 ​28 ​​ ​m ​3 ​​ ​ ​electrons ​​ . Calculate the magnitude of the drift velocity of the electrons in the silver wire under these conditions. Enter your answer in units of \frac{\text{meters}}{\text{second}} ​second ​ ​meters ​​ using calculator scientific notation (e.g., 1.23e-41.23e−4 for 0.0001230.000123).
