If I don’t pay school fees, can my school stop me from graduating and participating in the hsc?

Hey guys, so I just found out my physics teacher is not really a physics teacher and that the only qualified physics at my school is teaching the year 12 class. This explains why I have not been able to understand the major concepts because he is purely incapable of explaining it. Anyways, I was...

Can you guys recommend me any tutors who do 1-1 or classes for prelim and hsc physics. I am in desperate need of one because I believe my school is seriously behind and my teacher does not explain all the concepts very well.

The acceleration a ms^-2 of a particle P moving in a straight line is given by a = 3(1-x^2) , where x metres is the displacement of the particle to the right of the origin. Initially the particle is at the origin moving with a velocity of 4ms^-1. Show that the velocity vms^-1 of the particle is...

I have been given two possible questions for the in-class exam and my teacher did not explain the questions properly as he pretty much said "how does the context reflect context" but the hsc syllabus says how does the structure, form and features used by the composers denote the contexts or how...

Therefore it would be -∫-sinx/cosx.dx and by solving it should give you 1/2 ln(2)

derivative of cosx = -sinx

So far I have noted down that the main theme is the notion of 'life and death', along with religion and also paralysis in Joyce's Dubliners. However, I do not understand how I use these themes to link to each author's context and argue how their perspective was affected as a result. Also, do I...

Question is - Find the dimensions of the cylindrical can of greatest volume that can be made from 150pi squared cm of sheet aluminium. I solved that h=75-r^2/r and when I differentiated it, the equation came out as -2-(75-r^2)/r^2 and no matter how much I tried, I just couldn’t get r. I know...
