Helloooooooo :D can anyone link me to a solution of the 2011 mathematics solutions. Thank you

Americian -241 is used in smoke detectors as it produces alpha radiation which ionises air and is detected by a device. When smoke comes near the smoke detector the alpha particles ionises the differently with the smoke and this is detected by the device and the alarm goes off.

I look at it like this; validity is how valid the result is, so is it close to what the correct answer is, for example the heat of combustion, is the heat of combustion close to the known value. Reliability is how reliable your experiment is and it becomes more reliable when you repeat it...

Hey I did an assignment on Biopol, which is a copolymer of PHB and PHV, not sure if it will help but if you have any other questions just ask.

Hey try peer doc . net or hscguide . net if not just pm me

I was expecting you the say I finished hsc I don't even wont to speak about it ;) but aye as long as you get what you need :D and I would tell you how I went but I finished seriously don't even need to see, touch or talk about hsc again, hahahahaha nah they were actually really good thanks

Soooooooooooooooo... lol how'd your exams go?? and more importantly how's the bludgin

how did you get that mass, I got 6.699x10^-27 (4sig. fig.) by adding the mass of the extra neutron??

But you do not have the mass of the binding energy between them.

The question is stuffed, because the have to at least give you the mass of the deutrium, just realised, no need to worry Hypercomplexxx

Sorry, is this the right answer; mass defect 0.0024 u and the energy released 2.24 MeV damn, solutions lol

Are the answers by any chance 1.987 u mass defect and 1.7883x10^17 J?? oops forgot to use amu sorry sorry wrong equation is the energy released 1850.89 MeV

Ooooo so much to do and I'd say but PHYSICS ARRGGGHHHHHHHHHHH

hey there, can you do me a favour and check if the fitzzy book I gave you has Andrew's name on the inside cover. Thanks and do you still have that past paper book I gave you??

:haha: I have no idea what to do yet on friday but got to party hard ;)

Lol it does, like you said you finish tomorrow hahaha and haven't heard you call me that in ages Soosoo ;)

I said sulfuric acid but, I had said it was concentrated sulfuric acid in water as this will boil the water and cause it to evaporate, which will then condense into the watch glass altering the colour lol

Lol tohfa your the one with the exam tomorrow :p
