    emf

    When you explained your working did you mean dash as in derivative? If so, you have the right theory but remember that emf is opposite to the direction of change in flux, as represented by the flux formula. Therefore it is A, which you will notice is the negative of C.

    complex number euler form modulus question

    The most prominent method is to let e^{i\theta}=cos(\theta) + isin(\theta). Then use the fact that |x+iy| = \sqrt{x^2+y^2} The locus of z itself is an ellipse which would have been helpful in the old syllabus. However, there is still a geometric way to find the maximum value. Recall that...

    What would be the best way to self learn the hsc physics course/concepts?

    My method was as follows: Open up the ********* book, the pearson textbook (or jacaranda/in focus) and a physical notepad. When you come to a new section of a topic, read the ********* book first as a 'pre reading' exercise to orient you with the topic. Then read through the pearson textbook...

    Unable to view sources within past HSC history Exams

    Try searching for the names of the sources and finding out the information. I tried the link in source D and I believe that source might be the table on page 12 of this pdf https://historymuseum.kennesaw.edu/docs/how-would-you-vote.pdf

    Cambridge Ext 1 Dilations Q

    I would interpret it as a reflection in the y-axis. It's not undefined you just need to consider the new domain.

    Should I study stuff outside of syllabus for Mathematics Extension 2?

    Contrary to the opinion above, I think this is a very poor idea. The teachers should focus on covering the syllabus in greater depth rather than trying to force wider learning on students. Imagine if an english tutor made their students learn and examine books not within the prescribed texts...

    can i still get a band 6 or even 5 for english??

    In my first assessment task, a multimodal, our school decided to weigh it at 30% (higher than trials for whatever reason which was a complete dog move). I got a very low mark compared to the rest of the grade, pretty much the same situation as you, which was extremely demotivating. Throughout...

    Integration: Reduction Formula

    (1-x)^\frac{3}{2}nx^{n-1}=(1-x)\sqrt{1-x}nx^{n-1}=n\sqrt{1-x}x^{n-1}-nx^{n}\sqrt{1-x} Now you have terms involving U(n) and U(n-1) and so you can progress through the reduction formula.

    integration by substitution qn

    Let u = \sqrt{x} u^2 = x dx = 2udu 2\int{\frac{u du}{1+u}} 2(\int 1 - \frac{1}{1+u}du) And complete via standard integrals and change back to x. Determining substitutions is a skill you develop with practice. It is not always just to put the denominator as a variable, but try and imagine in...

    Private schools will never end. There will always be rich people that refuse to let their kids mix with the public school plebs. End of story.

    Module 5 physics questions

    Also, does the angular velocity change or is it constant at these two points and why? Where x is at a higher altitude than y Angular velocity is the same. They rotate at the same rate around Earth regardless of differences in their distance to Earth's centre.
