Was there a cheeky projectile?

is there a paper uploaded?

Just remember for the future that "equilibrium temperature" refers to the temperature at which an equilibrium occurs at the inputs. The wording is an example of poor communication. But what can you do? Just try what you can from the question and state an assumption of what you think it means at...

Basically, you want a point where the output is zero, which means that V+ = V- and hence there is an equilibrium that can be said about the inputs. Now, V- is fixed at 5 V (voltage division). We want to find the point when V+ = 5 V. To do so, using voltage division you can see that we want...

ENGG1811 isn't part of the core. You might be able to get it accredited as a first year elective, although that seems a bit dodgy so it might not be accredited. ENGG1000 can be accredited for Computer Science. You also might be able to get away with MATS1192 as a first year elective. Try to...

You are reading the graph incorrectly. Clearly the graph shows that when X_in < 0.375 V, Y_out = 16 V When X_in > 0.375 V, Y_out = -16 V

Yep so the flaw with HSC is that they don't teach you Kirchoff's laws. Although you got the answer out in the end, the following method may give you a bit of insight into how this actually occurs. If you don't understand it, then don't worry about the below and just use your old method to find...

I think it will show on your transcript as a separate section, but you will have a new and separate part on your transcript for after you commenced another program.

re: HSC Physics Marathon Archive Good point but in the question the effect would be minimal compared to the initial expected larger change in flux due to the magnetic field (the multiple choice options are suggesting this). The velocity change relative to the magnetic field would be quite...

re: HSC Physics Marathon Archive any way, I better do my assignment

re: HSC Physics Marathon Archive Yeah. When it enters the field, there is a change in flux through the split ring. This will induce a voltage in a certain direction, which is actually unknown as the voltmeter orientation applied is not known. However, we know that it will induce a current so...

re: HSC Physics Marathon Archive Nice succinct answer. Clear cause, effect and reason. Expand upon this point a bit: the eddy currents induced will therefore provide a breaking force, known as electromagnetic braking." You can use an equation here and state that this is also as a result of...

re: HSC Physics Marathon Archive I do agree with this case actually haha. However, he said "which opposes an initial change in magnetic flux" which covered his answer in the end. It would be nice to change that wording though. I like the use of "relative movement", so maybe "if relative...

re: HSC Physics Marathon Archive Next question: Explain how eddy currents can be utilised in electromagnetic braking.

re: HSC Physics Marathon Archive Btw I'm literally just copying and pasting syllabus dot points as questions here. It's good practice to ensure you know everything in the syllabus and have a solid understanding.

re: HSC Physics Marathon Archive Good answer. Would give it 4/4. You could also briefly say why it would burn out otherwise, due to a large friction/inertia meaning that a larger current must be supplied. However, what about the case of different types of motors? Just be a bit careful...

re: HSC Physics Marathon Archive You should mention a few examples for each as that is there practical applications (I should have made that a bit clearer in the question so I don't blame you) and need to say how they are different to each other and how they are different when they operate (as...

re: HSC Physics Marathon Archive Next question: Account for Lenz’s Law in terms of conservation of energy and relate it to the production of back emf in motors.

re: HSC Physics Marathon Archive The second paragraph was great! The first paragraph could use a bit of work. The tasks completed by what you stated are completely different in essence. Also, you should refer to them as solid state devices not "drives" lol. Also, can't really say "by...

I did it 2 years ago and have completed further study in pretty much all of the option topic. Feel free to post up marathon like questions in a thread here and I can help answer!
