i think you have misunderstood a part of chemistry. that is, the LHS HI chemical is a reactant andt he H2 and I2 chemicals are products, it does not have to be ther other way around,,,,that is its not as if reactants can only be two compunds and when they reactot hey form one compund which does...

what do we mean by acidic conditions????? does it mean the electrolyte is acidic or basic,,t hat is if it is a sodium hydroxide electrolyte we use teh 'basic' oxidation of water equation????????

for question 27,,,,wiht the ohms law. who thinks we had to subtract 2 form the resistance answer???????????/

i got 1:8..... think the direction matters,, 8:1 would be wrong maybe because it asked the new period to the original period which is Tnew/Toriginal which is 1:8.....but xcorrect me if im wrong

taht does sound correct ,,,but the thing is a radio wave travels the speed of light so it would reach the earth really fast so looking at c 0.63 adn d 0.78 the difference is 0.15. i think light woudl travle really fast sot hat if anything the time it woudl take tog et to earth woudl be small eg...

lol i had 4d aswel but the thing is i looked at it now adn realized that for that graph time is on the x axis adn hegith is on the ya xis ,,,in this experiment only height is the independant variable taht is it should bo n the x axis. so its either a orb ,, im guessing its b bcoz of the...

ye 15 has to be b,, bcoz it is a silicon doped iwht a boron that is it is a ptype semiconductor. and so there are holes. if we apply a potential as shown the valence electrons move to the left....(only valence electrons move in a ptype semiconductor, there are no conduction band electrons)...and...

k then that sounds good. but then where does the process of "scaling" get invlolved. that moderated assesemtn process isnt the scaling right?? if not then what do tehy scale, the exam mark, the moderated assesemtn mark or both???

lol this is what i meant, ,,, imagine a magnetic flux pointing up.......now imagine i hold a wireand i move it perpendicular to the flux to the right at CONSTANT velocity. as the wire continues to move in the flux is an emf genetrated....if yes ,,then is this considered a change in flux??

hey according to terry lee i gto 77%,,,,,anyone think thats enough for an E4 ,, maybe low E 4 or high E3?????? basedo n previous years wat was the E4 cut off?

does any one know if terry lee does 3 unti solutions,, and when does he post them if he does??

lol ,,i c so passing definitely gets an E3 ,,sounds good,,,,,i think max i can get is 57%,,hoping thats a mid to high E3 .. but hey,,,,,do you have to be above the average to get scaled up,,, for example say i got 57% and that was the state average mark,,, or say the stae average was 60%,,,what...

so what do you think the average will be,,,how far above the average must one be to get scaled up??,, i think i got max 70/120,,would this be enough for E4......... or even E3???????,,,

i answered from 1 to 5,,,,,,,,so tahts around 75/120 ,,,how much does anyone think would be enough to get bend e3 and e4 this year?????

no no i understnad that much,,,a change of flux by moving te magnet into the coil or vice versa because we are increaseing the mflux lines,,,but im saying this imagine we have a coil or a wire better to use a wire and say a magnetic field is pointing upward and we hold the wire and...

can someone please explain this......is a emf induced by a changing magnetic flux( ie cutting flux lines faster or increasing or decreasing strength in magentic flux) or is a emf induced when a conductor just moves in an external magnetic field,,such as say a flat metal sheet,, or a wire moving...

can someone explain this to me......i understand the process of moderated assesment marks(thanks to bored of studies) however i havnt found a forum that addresses this.... now assume a student ranks first in raw internal assesmetn mark and external hsc exam mark say 95 and 90 respectively, now...

this year my school isnt going well at all,, most people wont do well,,, im ranked first in my assesment marks with 90+ marks. now assuming i rank first in my hsc external exam with low to mid 90s in all my subjects and also assuming the worst case scenario where all my classmates get below 50...
