It's also good to mention the exclusion of the magnetic field from the superconductoru have to use meisner affect and explain the balance between the weight force and the force of magnetic repulsion resulting from the interaction
of the fields of the induced current and hovering magnet.
I would say A more than B although A is not perfect.... non of these answers are right. The real graph should look very similar to B, but it must extend below the t axis for at least a infinitesimal period of time. How would you get a moving stone to stop moving unless you apply a counterbalancing force?
help

if the answer is B, picture this: the moving stone gets to the bottom and then acceleration drops to zero. so the stone continues with a constant velocity after hitting the ground......???? dont make sense m8
so the graph must certainly extend below the t axis - but not for as long as shown in A
Maybe the one in (B) actually went below the t-axis for a tiny amount, but too small for our eyes to see.I would say A more than B although A is not perfect.... non of these answers are right.

InteGrand being racist wot (lel jks)Maybe the one in (B) actually went below the t-axis for a tiny amount, but too small for our eyes to see.
Impossible to understand at HSC level. I'd just memorise whatever the TB says for that (like Jacaranda).InteGrand being racist wot (lel jks)
I think the graph is restricted to when it stops the moment the rock hits the water
+ InteGrand what's your (HSC level) understanding of the Meissner effect?
F(c)=mv^2/rcan someone help with this mc
The infrastructural cost will also include changing all power stations to DC since superconductors only work with DC (Cooper pairs cannot form under AC since the Cooper pairs only travel in one direction)Since it's a discuss question, the only disadvantage I can think of at the moment is the technological and infrastructural costs required to cool and maintain the superconductors below critical temp.
Devices use DC and therefore no change is required from power station to device.What are the advantages of DC transmission over AC transmission (5 marks)
Ux = Ucos60hgow do we do this:
I'm sure you'd lose marks just because you didn't use the Physics method, although you'll get some marks for having the right answer.are we allowed use 3u method to solve physics projectile quesitons?
the x distance which is 45=Ucos60 * t, t=45/Ucos60Use delta(x) = Ux*t in order to find t in terms of U
I don't get what this formula is?
perfect i just got it thanksthe x distance which is 45=Ucos60 * t, t=45/Ucos60
do we take into account the mass of the moon or Earth?F(c)=mv^2/r
v=2pir/T
