hehe, sorry, cause the blue book call it a "exempler in the high range", guess i missed out on the last part. so correcting it, yea everyone look at the 20/20 exemplers from BOS cd for 2002. this is correct, the 2002 hsc is the only one with examplers, ie 20/20

yea, i read that before. too much info, overwhelmed and melt down of the brain occured. so i kinda kept off that site until after hsc

hehe, cool. did the idea come when i was asking how to become a mod? anywayz i didn;t get a chance last night, besides u got better qualification :) , are there any openings in phy, eco or eng moderator possitions? and who do u send application to?

i dun really get this graph really well so ill try to explain and any correction is appreciated. start: RBA monetary policy control the supply of cash through DMO. there for theoretically because RBA cannot directly influence demand of cash the demand line will remain constant. The supply of...

never came across these types of questions. is it hsc questions? would it be featured. i am kinda slow, so could someone please elaborate on the way to do it using both words and formulas?

hehe. books say that tv use mag fields to direct the direction of the electron cause its faster to change...( i highly doubt it) and difference one is entertaining (the tv of course) and CRO is for viewing change in voltage with repect to time. so things like heat beat and sound can be...

just adding to some brilliant information, the experiment was actually conducted many times around different parts of the earth and same result occured, which is null. Where the instrument is turned 1 whole revolution at 90 degrees each time and the interference pattern is the same, so the "null...

sorry madam, just that u stalk this forum too much and too quick to grab posts and providing info. its like ur running a monopoly. anyway this is from timmy, from the site hsc-mirror 5.2.2 describe how transuranic elements are produced Transuranic (elements with larger mass than uranium)...

wait, if it oxidises iron it would gain an electron and come out as gas but nothing would happen if it is mixed with cu solid right? cause there is no redox taking place.

thanks captain G3Y that was really helpful back to the iron argument i still reckon i am right. anywayz which topic is it from or like did it ever appear in a test?

hehe thanks, alot clearer. but would the displacement occur if the metal have a lower oxidation potential than hydrogen? ie: cu with reduction potential of 0.34

thanks, so basically Increases strength and hardness at high temp and how does chronium help to resist corrosion when added to iron. and is steel iron with 1.5% carbon? and do we need to know those thing like wraught iron and stuff with diff amount of carbon in them?

damnit, always 1 step behind u. i was just typing u know........now it seemed i copied what u said!!! oh can some one post up there notes for that dot point. i still have trouble getting it.

i know that a transuranic substance is one with higher atomic number than 92. and all transuranic elements are made from uranium bombarded with neutron. but what other difference in production does it have with commercial isotopes. oh and can lower atomic number atoms be bombarded with helium...

lol, thanks for that. thought that this forum is going everywhere with question might as well come out with another random...

could u elaborate on ur second point on metal and acids? what u mean by displace?

lol, ull prob get a 4th answer. i think u should stay with grey green for iron(ii) anywayz can anyone answer my question on steel?

whats the difference in the production b/w commercial and transuranic elements? also many people tell me that u can;t bombard with helium nuclei, dun know y

acid used in those fish can thingy to neutralise the fish smell from ammonia and stuff produced by dead finish. best use ever

dreamo, u know when u make synthesis radio isotopes u can either do it on cyclotron, nuclear reactor and linear accelerators. cyclotron can only bombard the parent atom with proton while nuclear reactor and accelerator does both proton and neutron. is that right? also i dun get it why u can;t...
