with the meissner effect, does the magnetic field come from eddy currents or from the magnetic field that the cooper pairs produce?

When stating whether they attract or repel, can you just say because the current is in the same direction/opposite, or do you have to explain why?, ie the magnetic flux density being less between the wires when flowing in the same direction thus they attract etc

confused as to why different answers keep alternating the aim of the experiment between proving the aesther and measuring the speed of the Earth through it?

Also, do we need to know in detail Thompson's plum pudding model when discussing the Rutherford dot point?

hence the original questions, cheers for the help though

So what would I classify the work function etc under?

Is the whole photoelectric effect encapsulated with in the dot point: Identify Einstein’s contribution to quantum theory and its relation to black body radiation? I'm confused as to where this whole section of the book fits into the syllabus, thanks.

Many essays are being passed around my school and there's a chance that they may be used numerous times, how do they distribute the exams among markers and what happens if two essays are very similar?

I think I went well but won't be sure till results come back tomorrow! All the advice I can give is to obviously get a good sleep before each exam if possible, which wasn't always for me as I was a tad underprepared, and just walk in feeling confident regardless of whether you know everything or...

We had trials first two weeks :D

awesome, cheers for the help :)

so basically as soon as I see the change in colour of the indicator, end the titration?

bump

I need to write up a procedure for this titration but I am confused due to it having two equivalence points. Is there any difference in procedure compared to a monoprotic acid? thanks!

How much for each?

Hey guys, What do reckon the atar will equate to with these ranks: School rank: 42 Math ext 1: 1/49 Math2u: 2/68 Chemistry: 1/31 Physics: 2/42 Economics: 9/43 Eng adv: 35/121 Thanks :)
