Hey, can anyone SERIOUSLY do ANY of the advanced 3-u questions, especially the conics questions, in the Fitzpatrick 4u book? I havent been able to get question 1, 2 or the rest. Is my school just dumb or are they made impossible?

they invented a little thing in the past few years called a mouse, right.. so then what you do is.. (this is so genius..) you cdrag you mouse of then information... all while having your magic little finger on the left button of the mouse.., then you let go.. and click on the right button... so...

You are damn right! It is Elias .... dont know about the stopping voltage thing though.. wtf is going on there? :\ ... weird stuff.. elias stick to 4u maths m8 ;)

DO u have the Jaccaranda Physics text book? Its in the medical physics module and has quite a lot in it. Physics in Context also has the option of medical physics and so there might be some information that you can plagerise from there. :)

Mr EaZy.. What school do you go to? Would your name be attia by any chance??

tell ya what, i used scurvy last year, and got full marks for every question i attempted. WHY? because the only things you have to know is that it is the deficiency of vitamin c aka asorbic acid. it can be brought about by not feeding ur baby breastmilk at a young age long enough or by an...

Is there like written work for food tech? Man i want to do food tech as a subject but the principal wont allow it as a HSC course, specially to us guys. Pity. We get stuck with 4u and 3u Maths, Physics and Chemistry all day. 6 hours a damn day.. 4 with the same bloody teacher!!... EVERYDAMN DAY...

Pretty simple isnt it?

May i also add, mr kheir, you are a total imbissile. It says above that that was your first post, and im afraid your are not off to an intelligent start my dear misguided friend. I hope you will wake up to yourself soon, because the HSC is not too far away, and this immaturity will get you...

yes thanks for your input as well mr ashtor, however, you too, like za, have misunderstood my question. i understand that it was later disproven. however, the question is sir, that at that time, some hundred years ago, did Hertz's incorrect experiment support the wave model or particle model...

thanks alot za, but im sorry to say that wasnt really what i was asking. what i am asking though, is at the time that they didnt know if the cathode rays were particles or waves. what did that experiment by hertz support? the wave or particle theory??

.

try getting it laminated, ie. getting it sliced into as many pieces and glue them back together, reducing eddy currents ;)

(Revised) Particle Vs Wave model of Cathode Rays Ok, for the fourth time, i finally realised wat i asked in the question.. so here it is... In jaccaranda physics, they say that the fact the cathode rays did not APPEAR to be def;lected by electric fields (by hertz which turned out to be...
