wrong noob, and your magnetic field strength is wrong lolAlso you place the mass on side Y. 100% positive.
its called a trick, they made the answer to be a real big number to catch out the noobs that dont believe in themselvesHaha I got x10^21, but then I was thinking hmm...
Who got the frequency of the lightwave in the 2nd last question from the experimental table to be 8.something x10^-14?
Also i think u place it on the Y side. I fucked up the length contraction and time dilation question, i hate those questions because i feel i cant interpret them proper. Stuffed the projectile question, didnt even realise it was a projectile haha, thats 6 marks or so gone.
On side Y, use the right hand palm rule (magenetic from left to right, then the current goes forward) so the force is downward. Therefore u put the mass on side X to balance it out. Isn't?Who got the frequency of the lightwave in the 2nd last question from the experimental table to be 8.something x10^-14?

lol, they specifically said constant acceleration in the question, and they asked for a time, and the shape was a parabola, one would be thinking projectiles
Shouldn't it be quite big, since c=wavelength *frequency. The wavelengths are 10^-9, therefore the the frequency should be around around 2*10^15. Though I have probably done something ridiculously stupid.Who got the frequency of the lightwave in the 2nd last question from the experimental table to be 8.something x10^-14?
it's side X, but ur rite with the 0.098TSomeone post up the question and I will show you why it is Side Y. And why 0.098T is the correct B.
I was tossing up between Wb and Teslas too... and i put Wb ><"1. C

..Multiple choice was hard
16. a) 4900
b) 1.3 * 10^21 Edit: I think I changed this into something like 2 * 10^5 or something, not too sure
17. Wrote about a plum bob hanging (to determine interial/non-inertial FOR)
18. a) 760 light years
b) 2.4 * 10^10 seconds (I used 365.25 days in one year)
19. a) 1.602 * 10^-16 N downwarsd
b) 5.9 * 10^-8 seconds (that was the projectile one)
20. I used induction cooktop, loudspeakers and a power drill
21. a) X
b) 0.1176Nm downwards
c) 0.049 Wb (I know, it's meant to be Tesla, FML)
23. a) Left
b) 8.3A
c) Left (towards W1)
24. a) Band E
b) Band F, 0 -> 1.3kg
25. a) Opposite charges
b) 2.5 * 10^-2 Wb (yes yes Tesla fuck you)
And yeah Quanta was pretty straightforward
I want to know which ones I got wrong, thanks
P.S. I had enough time to write all my answers on the data sheet
Yeah, that was an easy exam.. Still managed to lose heaps of marks
Edit: I remember I changed one of my answers, I think it may have been 16 b)
Or this guy could just explain it perfectly. Also with the B field:If you noticed there was no south pole next to the y, no magnet at all infact, there was just one magnet on side x, meaning that only x is exposed to the magnetic field.
Current flows from Y side through to X, meaning x is going downwards.
I could be wrong, the question was very open to the interpretation of the individual, thus why it sucked
