SAy analgous to diamagnetic because it isn't diamagnetic. Meissner effect would be a better way if identifying that. OTher things, can't remember what others have posted. Critical Temperature Critical MAgnetic Field Strength

With Beta decay, you are obtaining the energy from within the nucleon (neutron) that is breaking down. With fusion, you are obtaining the energy from the rearrangement of the neucleus and the difference in binding energy due to this.

Fission reactors do not end up with the fundamental particles, rather they end up with smaller atoms. If you calculate the mass of the reactants and products, there is a deficit between the two. This defecit is then released as energy.

Ok, I haven't read up on how guitar pickups actually work but there is an induction process present. I'm not sure ifts produce an induced current that is being detected or producing a back emf and the resultant drop in current is measured. If they had an open ended question like in Q20 2005...

Simplest example is to have an induction coil with a spark at the top. Tune a AM portable radio off station and when the spark occurs in the induction coil, you hear the result in the static of the radio. You can tune the radio to the frequency of maximum static to identify the most common...

With an induced EMF, you are increasing charges potential. It is like pushing water up hill. Once the induced EMF has increased the potential, it then flows down again. So the induced EMF pushes the current to the positive terminal, it then flows if an external circuit is present from...

You won't be marked down for this at the moment but you will be marked down if the answer is not coherent. That means if you waffle on and do not have a structure to the response you won't receive full marks. It is not unheard of people writing 5-10 pages and receiving 1 because they don't...

CEM, I know the answer in sicences, only one of the options are judged. Do you know what they do in history?

The positive ions make up the lattice. The lattice is the structure and influences.

Your first answer would have given zero as it is irrelevant to the question. After the disaster of the results, the examiners enable a remark that allowed motion around the moon but it actually is irrelevant to the question. They were after a discussion of the reentry and landing process...

Once again it comes down to the level you are expected to know at the HSC. Collisions with the lattice would be accepted. Technically it is the collisions with the lattice defects - the structural and vibrational defects...

EMF is minimum when perpendicular to the magnetic field for a standard generator. Look at the picture in my earlier post.

SCaling and aligning are very different processes and result in very different marks. Read the stickys on both.

Bigger problem is it didn't answer the question. Remember your KEYWORDS. Compare, means to state similarities and/or differences. Just describing what happens won't obtain full marks.

That is wrong. Look at the standard graph The change in flux at the maximum flux is zero and no EMF. Think of the slope at the point.

Yep TYPO, fixed up.

I assumed he was referring to scaling not moderation because the quality of the students affect the process and is often referred to.

REmember Faraday's Law Its the change in flux that is important no the magnitude of it. So whenever the change of flux is a maximum, the EMF is a maximum. So for a normal gnereator, when the flux is a maximum, the change in flux is a minimum and so is the EMF. Think of what is the slope of...

The hardest part is ensuring you carefully read the question and what they are assessing. I know that one of the commercial answers doesn't address the question for the 2005 paper. They made the same mistake as Shanks That question is only about the landing of the rocket, all the information in...

Once again, it depends on the angle given. You are currently doing exactly what they wanted as a distractor in Eg Q7 in the 2006 paper. http://www.boardofstudies.nsw.edu.au/hsc_exams/hsc2006exams/pdf_doc/physics_06.pdf The angle is not the one represented by the one in the formula. You needed...
