might be a naive question, but concerning the blast furnace:
they blow pure o2 through the raw iron to oxidise impurities like carbon etc, but that would mean that exactly the right amount of o2 would have to be blown through before the iron also started reacting, which in turn means the...
can't speak for the AP but A-levels suck :P. the only maths in the entire physics syllabus was the exponential function (for capacitors and radioactive decay) and some other bits and bobs, arithmetic etc. didn't even have to know how to derive them...just rote learning. fluid flow and a decent...
theeen my gauss is wrong...may have been the way I've learned it - via the "number of lines" instead of a formal mathematical integral.
when I learn my latex (after tomorrows exam then) I'll clarify what i meant.
ed: actually i think i figured out what I did wrong now, post tomorrow :D
ok, from common sense POV that's fine.
the further question i suppose, is why the two (bold) word equations simplify to the same thing, when one is for a single charged plane, and the other is for 2 opposing ones. (presuming I've made no mistake)
obvious question IMO, but just need to make sure before test.
if you have two parallel conducting plates, and apply charge to one of them, then the field between them is half, compared to if the plates were acting as an air capacitor ie. both plates oppositely charged?
thing is, when I use...
well usually it'd be accompanied by a follow up such as "if i buy this magnetism quantum ray blocker from www.scam.com will i be cancer-free"...not suggesting that anyone on this forum would ask such things :)
anyway, back to topic. the study muad mentioned is on a high voltage transitory...
this isn't a quack question (is my monitor giving me cancer...etc) but are there any studies involving effects on humans of considerable static electric fields? say low thousands of Vm-1?
what could be possible long/short term effects?
hold a sandbag/other equally random object in your hands while standing on some bathroom scales. now yank the object upwards as fast as possible, and observe the scales (this'll be tricky, pulling and observing simulatenously). put simply, there is your "opposing" force.
not quite right...fructose is a sugar which actually doesn't cause a very large insulin jump (compared to eg dextrose). you can check it against the GI tables, which seem to be in fashion lately :rolleyes:
From what little I know, it's converted to liver glycogen only...so if this has...
Can't say I totally got it from your post, but the word hyperconjugation led me here

graphics make it a bit easier. thanks in any case :)
