well i always forget to go back and cross my t's and dot my i's cos im in such a hurry but i reckon that they can figure it out with a bit of brainpower and they must have read millions already so they just get the general gist of the sentence and unless they're spiteful hopefully they won't...

well it could be basically anything so just grab the cd nearest you and analyse the first song, then try and get hold of something classical, alternative, whatever really. It's best just to train yourself to get used to hearing something you've never heard b4 and force yourself to analyse it...

yeah i think the CH2CH3CH2 way is a 'condensed' structural formula, but in an exam situation they're not going to ask for a huge molecule so i just do both ways. I usually need to draw the one with all the sticks first to see it properly and then just write the 'condensed' way underneath it...

well i've done all my summaries now and i didn't come accrossany dot point requiring that! So either i missed something or... no i think im right. We don't need it

i use specific heat = (energy supplied in J) / ((mass in g) times (change in temp)) it's basically the same formula rearranged, but i find it easier to remember in words.

i reckon there's gonna be at least three and at least one with no relevance to the actual material, as in how can you improve the reliability blah blah blah I hate those questions

I'd go in a bit more depth for polyethylene. You need to know the two different processes cos each one produces a different type of polyethylene with different properties and uses. Gas phase process produces low density polyethylene (LDPE) this is the one you already know Ziegler-natta...

Not if you're in the same inertial frame of reference it's not, you wouldn't be able to tell the difference. And if it's an observer you'd have to look mighty quick to get a look at their watch whilst you flash by at the speed of light!

I go for 2. If the speed of light in both directions was identical, then the waves would return in phase and add constuctively. Any change in velocity would result in a change of phase of the 2 waves. But cos they didn't know the direction of the aether, when rotated by 90 degrees the...

I think this is mass dilation So when it's accelerating you keep feeding energy into this huge blob but by e=mc^2 all your energy just keeps getting converted to mass so it requires more energy which once again is converted to mass...etc. it's a vicious cycle

Im jealous!!! I want a physics professor in my house

during reading time i work backwards from the end and i usually just finish the theory questions so then i know all the tough ones i'll be facing later on. Then i do the multiple choice first, meanwhile letting my subconscious fetch all those answers for me) then head on to the theory in order...

aah i get it now. So the time dilation is the cause for an observer, whilst length contraction is the cause for the space ship (moving frame of reference). And the effect for both is that the ship goes a lot further in a shorter time thereby consuming less fuel. Thanks guys

i don't know about the percentage thing but yeah it can be really repetetive...that's a good thing tho! for the information gathering points where it's more research than a prac do we have to be able to name our sources and where we researched??

do we need to memorise the end points of all the different indicators?

do you mean five skrzynecki poems?? cos if u do how the hell do you manage to write a decent amount about each one in 40mins?

If that was the only reason then yes i think it's unfair and your teacher really sucks abdooooo!!! . It just means they can't think for themselves and see that your answer said the same thing in other words. pfft to yr teacher, i feel sorry for you

doesn't urine contain ammonia?? anyway theres been a post on this b4 not that i think it contains much more enlightening info then this one really

hmm i don't really understand...is there somewhere i can read about these isotopes?? Going by the muon theory, they should only be able to travel a short distance, but they reach earth becos of length contraction right? In their own frame of reference their time doesn't slow, it only slows for...

nope nope nope. Never ready enough, they always seem to be able to chuck in a question that throws me. I may seem pessimistic now but i have this technique..just repeat Im gonna ace this!! to self many times b4 test and you'll be fine!
