.. NO and ill be real pissed if im wrong cause i went real crap in other areas. But u too will be pissed if ur wrong.. lol\ Oh shit ur right im talking about eddy currents causing the poles to be generated but to have them in the first place it needs to be closed...

.. Yeah 1 and 3 are artificially induced or whatever and 2 is a natural alpha decay due to normal instability ( excessive neutrons to protons if u wanna say)

.. I think the whole exam was a waste. They put weird q's. I wanted the how stuff works stuff. Like Ac Motors , Dc .. Ac vs Dc, Silicon vs Germanium, Safe reentry.. With these weird q's i found it hard to express my knowledge.. and what if u misread a q like the solenoid... 4marks (i didnt...

.. Nah its about the space-time continuum for relativity. Time is not absolute..New thinking. And einstein said that the radiation was quantised and not the atomic oscillators in the black body... Maybe they'll accept a lot of answers. They might all be close to the criteria??? hope so.

.. oh shit ur right... :chainsaw: But then again think of when a magnet is dropped in the aluminium pipe.. Yeah current makes the electromagnet when u wanna magnetise a ferromagnetic material.. BUT the whole think about induction is the force isnt due to it being an electromagnet...

... I am pretty sure and better not be wrong that the force acts on both of them. The external circuit just allows a current to flow (driven by the induced emf) but its not what creates the force. Lenz's law is stated as "a change in flux gives rise to an induced emf , the direction of...

...

... Oooo thats an interesting way(easy too) Mine was probably half right(and crap long way) x = rcos@ y = rsin@ i d/dt ( ) both sides twice for x and y x* = -rsin@ d@/dt = -r@*sin@ x** = -r[@**sin@ + @*cos@.d@/dt ] = {-r@**sin@} - {r@**cos@ } did the same for y and...

i m stinky

.... i felt like killing myself :chainsaw: But i wont. ive been wasted this whole year just from this exam. and i was Completely furious and burned my paper when i got home. Im feeling real stuffed now. I Still love maths

... oh so a>q????? I get it now thanx all

... I still dont get the last part therefore every factor of q is a factor of a if every factor of q is a factor of a ----> q=a right??? so q/a=1???

... thanx for the reply but since gcd(p , q) = 1 WTF does that mean?

... I really dont get this q/a = p^3/(3pq-bq^2) the bottom part is an integer cause p,q and b are(given) they say q divides a cause p and q have no common factor (also given in data) I DONT GET THIS????? why

... what do u guys wrecken the hardest yr's for 4u are so i can practice some. I havent done much and have less than ... days.
