GO AND READ THE THREAD!!!!! it's B.

and what degree qualifies you to make that (incorrect) assumption?

but the distance change of the moon when it's in front and behing is so small considering the solar system... could be could be not... idk 13/15 now :(

did two pages and 2 lines on the 6 marker... what about you?

MOST WIN EVER :D you should go into the textbook industry! Q2 is calculatable from infromation given so 9.37.... i.e. (A) 4 is D 5 is C 9 i got C, this is being debated 15 is A: E field is uniform.

i hate it with this NEGATIVE EP

It has been done before :P

BUT, the students must know the impacts of their future career, instead of blindly stepping into something capable of destroying the world.... <cough> LCH <cough> There sould be a concentration of maths, but the impacts must be sudied- not necessarily examined.

I just think: electron flow is opposite to conventional current... every time. But the force's direction is the problem i have... maybe 14/15?

But you out of all people definately have the ABILITY. It must have just been stress...

NONNONONONONONONONONOMNONONONONONOJNONONONO!!!! Force is the force that pushes it through the field, not the induced force!!!! That being said, the same rule applies to a current carrying conductor in a B field...

Did I really get 15/15? awesome!

They were hard indeed, but i believe they gave too many marks for the simpler ones. ran out of other creative questions?

cos@ is the agnle of the coil - 0 degrees at start sin@ is the angle a wire makes with the magnetic field

Re: Above Did anyone see Astrophysics part E? whaeres my maths cushion gone??? i wanted maths!! Predictions: someone got 100% i got ~98 raw

two letters: E-f*cking-Z

I liked it, becasuse it related to modern developments in physics. So, who else got oppositely charged particles, proton from right to left, electron from left to right? Also 2.5 x 10^-2 Teslas for the field. That was the hardest question from me. Even Q30)e) was easy in comparison.

the way i tought was that the Cooper pairs actually CREATE the vibrations, so not A. not C or D obviously. so B.

well, in 11, (D) starts at zero, so wrong. its not asking for the force perpendicular to the coil, but the force ONLY on AB. for 13 i got B but im not too sure...

11 is definately NOT D. the force on the wire is constant and up, until the commutator switches it.
