found it thanks, according to that I got 17/20 in MC, not great but seems everyone had their problems in it so its ok i guessIdk if it will let me say the site name on this without getting banned. It's just in hsc exam discussion 2017 for another site if you look for it you'll find it
They don't use the meissner effect to levitate the traini wrote it could carry large currents cause no resistance below critical temp and it is cheaper to run than conventional electromagnets cause no resistance meant not as much energy loss due to heat maybe that's the same point tho
yeah with rapidly changing electromagnets.Yeah i didn't say that in my answer. But to levitate it, don't they use repulsion by using the same pole on the train and on the tracks?
Pre sure from the top, the proton is moving in a parabola instead of north westThe radiation question was bs had no clue what I was writing
Proton I half bsed it but hopefully my north west helical shape was right
To the person above, range was found using delta y = 0, finding t and subbing back into delta x.
I put that too but P is negative turns out since it said "circuit" hence positive charges come out of the positive terminal. If it was just a wire it'd be P but nah
3.5 is used cause it has less interaction with bodily tissue so is used as sector scans imaging e.g. Babies in a mothers womb. Lower energy sound waves interact less with tissue so can "reach" further into the body, but as a result has lower resolution.
