Doubly‑charged calcium ions, Ca 2 + , are released into your bloodstream and flow through your capillaries. The diameter of a capillary is about 7.50 μm, calcium ion concentrations are approximately 1.10 mol/m 3 , and typical electric current flow due to the Ca 2 + Ca2+ ions is around 1.2 nA. Calculate the drift speed v drift vdrift of the calcium ions.
