Replies to: Some advice for those taking Chem/Physics in June
Wilchartermage - someone asked me this in a PM. I sent them this:
Just know these points:
Superconductivity - The complete (as in EXACTLY 0) absence of resistance in a substance (as well as a lack of internal magnetic field). Most commonly occurs in supercooled metals.
In short - EXACTLY 0 Resistance, No internal magnetic field, and VERY COLD Metals (but NOT absolute 0, that was a trick answer on the CB book's test)
Superconductivity was on the test I took as well, it was very similar in form the the question in the CB book but I've forgotten it. It was easy though, it only tests those concepts above.
Chaos Theory - The complicated version: "chaos theory describes the behavior of certain dynamical systems – that is, systems whose state evolves with time – that may exhibit dynamics that are highly sensitive to initial conditions"
The easier version: Chaos theory is the issue of whether or not it is possible to make accurate long-term predictions about the behavior of a system. The key postulate of Chaos Theory is that is is IMPOSSIBLE to make those predictions (well you can but they'd be worthless).
A common example of Chaos Theory is also known as the "Butterfly Effect," where the originator of Chaos Theory proposed that a flap of a butterfly's wings could spark a chain reaction that started a tornado a thousand miles away, and thus it is impossible to make long term predictions of weather.
Chaos theory is actually a lot more complicated (and very interesting), but that's all you should need to know. I can't possibly imagine the SAT testing chaotic dynamics, etc lol
Good Luck!
physics equals OK class
I used it for the May test (and I was in AP Physics) and did horribly ....<650.
What about sparknotes?
my friend did the same thing and recieved that mark
For chemistry, how important are solubility rules. they didnt show up on the ap test.
But to make sure, you could post the first question or two from it
if so, did u find it helpful?
