ok. this question is simple you just have to get your head around it. from the particles perspective (which is travelling at 0.6c) the length of anode to cathode is contracted. just imagine it this way, the electron particle is standing still and the anode and screen is moving at 0.6c, as it is...
dont be overly confident. in the trials i thought i did exceptionally well and only got a mark of 75 ... and yes my teacher was a very very harsh marker. im just hoping for a band 6

thats the paper credit to helper
if you want to double check ... basically 0.75mj is the correct answer.
sorry its wrong ... if you do 3 unit or 4 unit projectile you would know when it lands the horizontal is not zero or either the vertical if you are moving upwards and landing
is that the correct wording of the question because i remembered it goes how much more energy is required to move from 80 000... so if its at 20 000km already tthan wouldnt it just be 20 000 to 80 000 ...
no because it goes what new arrangement can be used ... the only two that would have been correct was perpex and copper... but perpex doesnt conduct electricity so i cant see how that works
nope. heisenberg is the uncertanty principle - theres a limit how precisely momentum and the position can be found.
pauli's exclusion -no 2 electron's can have the 4 same quantum numbers.
yeh i got it too but my friend said it was from the centre or sumthing so you should add a 1 too it....so it will be 1.75 mj but i cant remember what the question asked... i thought i remembered it asking how much more energy is required but he said it was from the centre ...
but yeh its...
Re: How Many Pages?
i wrote altogether 28-29 pages (2 booklets each) and this girl in my year - 3 booklets each module so thats like over 12 pages each ... thats nuts
ok
module a - has not changed text type from an essay since new syllabus
module b - has not changed text type from an essay since 2002
module c - has been changing constantly
so my prediction would probably be A and B maybe 1 of the 2 but could be both,
i want an interview i hate...
