he imposed his postulates on it (in a nutshell)

adam....they are both inertial frames of reference. yes the spaceship is moving and the earth is standing still from earth's reference. but the question asks what the spaceship would see, so you have to consider from the spaceship's frame of reference, ie; the spaceship is stationary and the...

adam its not "one moving one not moving" they are both moving relative to each other there is no such thing as "absolutely stationary"

^ electrons don't repel magnets currents do

depends how difficult the examiners decide the exam was....i doubt it would be as high as 90

that's right except that you would need to say an emf was induced in the first, not a current. a current by definition moves so "a current with nowhere to go" is not a current.

fuck are there really moderators in a bomb? and control rods and stuff?

scale doesn't hurt but yeah if you identified 0,0 and the point from the first test it would be right

iH that's incredibly wrong figure out the direction of the field one wire is exerting on the other then think of a moving charge in that field same direction = attraction

juber it said in the question that it went round in a circle of constant radius hardly rocket science

yeah talked about strength at different distances (extremely close, neighbouring nucleons, any further than neighbouring nucleons) and also that it was independent of charge

does anyone here actually understand general relativity? i know i've got no idea, except i'm pretty sure that we don't have enough info (eg; nothing about acceleration) to work out the question according to general relativity and using special relativity, b is correct (dammit put d :))

yeah that's what i did rage

f=mv^2/r has absolutely nothing to do with quanta to quarks its the centripetal force straight out of core topic 1, space (core 1 section 2 to be exact) whatsmore its vital because it demonstrates that you need to increase the magnetic field as you accelerate it, proportional to the...

nah spyder its in the air the same amount of time for each test vertical motion is unaffected by changes in horizontal speed

nor did it talk about mass dilation....but it did talk about magnetic fields so clearly you need to talk about the effect of the magnetic field on a charged particle, namely F=qvbsin... also saying "accelerating it past the speed of light is impossible because it requires infinite energy" does...

clearly they didn't intend for you to talk about eddy currents

that's exactly what i did also made it up on the spot i used an ammeter instead of a cro but same thing really

i thought this too because compare needs to point out similarities and differences, i said both had three quarks and that each quark was one of the three colours. then obviously just spoke about charges and which quarks (uud and udd) were in each. not much else you can do

sique i also did the hand cranked generator...how did you talk about controlling other variables? namely the speed at which you rotate the generator?
