At the moment i'm trying to cut down on calories, so weird diet i've invented involves taking Metamucil (dietry fibre supplement) in the morning, which seems to fill me up, and apparently dietry fibre isn't really digested totally or something, and eating quot;cup of soupsquot;, which usually have between 260-360kj per serve (not sure how many calories this equates to)Plus a healthy meal at nightI'm also drinking heaps of Diet Coke, Fanta etc, because the kj are so low and it seems to fill you up, is there any negative side to this?
This Site Might Help YouRE: drift speed of an electron problem? An aluminum wire having a cross-sectional area of 5.00 x 10-6 m2 carries a current of 8.00 AFind the drift speed of the electrons in the wireThe density of aluminum is 2.70 g/cm3Assume each aluminum atom supplies one conduction electron.
Excercise, drink water (avoid soda or keep it to a minimum even if diet!) And eat fruits, veggies, and lean proteinEat 5-6 small meals a day.
InAvq or in english: current in amps number of charge carriers x cross sectional area (m^2) x drift velocity (m/s) x charge in each carrier charge carrier being electronrearrange the equasion to find V V I/ nAq and put the numbers in!! or wait for another answer to give it to you ;) hope that helped.
The number of electrons entering the wire is 8/1.6E-19 per secondSuppose that the wire is a meter long; the drift speed can then be calculated from the electron input rate (which we just did) and the electron density (we're about to do it)The volume of the wire is 5E-6 cubic meters; its mass is that times 2.7E6 grams per cubic meterThe 13.5 grams of aluminum represent 13.5/27 moles, or 3.011E23 atoms of the stuff, or that many conduction electronsWe're inserting 5E19 electrons per secondDividing 5E19 by 3E23 gives 1.66E-4 meters per second.
