Um, i have a different answer to you all :P equation of form 2A ----> B to simplify it given info: 0.132 moles of A INITIALLY 0.04 moles of B at EQUILIBRIUM from 2:1 mole ration, 0.08 moles of A must have reacted to form 0.04 moles of B therefore, A at equilibirum = .132-.08 k =...

You work out that there are 0.15 moles of HCl: You work out how many moles of NaOH are used, something like 0.0138 or something. Then u realise that the amoutn of carbonate must have neutralised (0.15-0.0138) moles of HCL. You then halve this due to equation and multiple by molar weight...

18 for the essay, 12 for the creative, but I had preprepared answers for questions almost exactly the same as those we were given and so they only needed some reworking.

Some extremely generic questions that were extremely well suited to preprepared responses, both the creative and the essay. Whether thats good or bad depends on whether you knew your stuff or not I guess...

i used one and a half booklets, though i dunno how many pages that is. Remember its quality not quantity though :)

But seriously, what a win for pre-prepared essays and stories *laugh*. The creative piece was as general a story as you could ask for with just a slight maniulation of open-ended stimuli and the journey question was just your generic essay question. What an easy exam :)

That was me btw ^^^. Also, in resposne to: "AND i think you are thinking too much about this concept, you have like made up your own theories and stuff, juss concerate on the HSC then in uni or wwotever u can make up ur crazy ideas." I simply make the point that perhaps you should think...

I don't see how i can make it any clearer.... if the speed of light is constant (as Einstein proposed), an absolute frame of reference (the ether) cannot exist.

I see your point. A better answer would be that there is never any proof in physics. People (such as Einstein and De Broglie) make hypothesis' and then experiments provide support for or against these ideological frameworks.

Ark: please let me know where i go wrong: (1) The ether was a proposed medium for light which had the KEY property of being an ABSOLUTE reference frame (2) Einstein proved that the speed of light was constant These two statements are fundamentally incompatible. If there was an...

Serge: If his theory was correct, then Einstein did in fact prove the speed of light was constant. Results and predictions based on his theory were later VERIFIED by experiments which lends to the belief that his theory is correct (or needs only minor refinement).

If you define aether as an absolute frame of reference then it is completely imcompatible with special relativity. Special relativity says that the speed of light in constant. Yet if light travelled through the aether (an absolute frame of reference) its velocity would become relative to the...

If Einstein's 'Special Relativity' is right, there is no natural rest-frame in the universe. Therefore, there can be no "aether" as it is commonly known, because if there were, it would provide the natural rest frame, and affect the speed of light as measured in other moving inertial frames...

You are correct nosadness. As a side note, only superconductors exhibit this effect (to this extent) as no current is lost due to resistance and hence the induced current/magnetic field is exactly equal to that which created it.

I am afraid not. Einstein proved that the aether did not exist when he proved that the speed of light was constant. To demonstrate this, let us assume that the aether DID exist, and thus provided an absolute frame of reference. Light travelling in this absolute frame of reference no longer...

The equation 1/wavelength = Rydberg's constant(1/(n final)^2-1/(n initial)^2 was first developed in another form by Balmer as an empirical equation to describe the observation of the visible spectrum of hydrogen produced and observable when hydrogen gas was excited by the addition of energy...

Because Serge, as a Swiss clerk, Einstein never even heard of the MM experiment. Simply because it had been done by that time did not necessarily mean it was a stimulus in the formulation of his theory.

How does Einstein's theory of special relativity explain the result of the Michelson Morley experiment? (4) this is a short answer question in HSC 2001. can someone please help out? Einstein's theory was developed without knowledge of the MM experiment but it does help explain its results...

sorry my bad, that was a typo :P JumboKHS is correct

Syllabus answer: No. Proper answer: Currently no solitary quark has ever been found although there are good theoretical reasons for believing they exist which I won't go in to here.
