For the rocket question where we had to find the mass of a planet using conservation of energy, do we equate the change in kinetic energy with the change in gravitational potential energy? so 1/2mv^2 = GMm/r (m= mass of rocket, M= mass of planet)

Also for the last question about testing whether the hypothesis was true, you had to say that the gravitational force of attraction was insignificant to account for the centripetal force since it was too small, right? By comparing GMm/r^2 and mv^2/r

will 90 raw mark be scaled down?

"Derive Maxwell's equations of electromagnetic wave propagation using triple integral techniques“ （5 marks)

Hopefully it's not as hard as 3u or 4u

there's no way wtf, what's the point of getting 90 raw mark then

Please I really need to get in my course 😭😭

guys was this the answer to 14)a)?

But how come there's horizontal asymptotes when y can be any value?

Maybe I'm wrong, but didn't B and C have horizontal asymptotes, so it couldn't be the answer? Because since y can have any value, and also sin(y) ranges from -1 to 1, so dy/dx has to range from 0 to 2

Oh I got D for that one

Wait what was the question again

But honestly tho those last few questions were pretty hard

That hard af test got me contemplating my life choices. Or am I just bad lmao

Thanks for the insight, I was wondering if I can sort of neglect English, and be content that I can get at least band 3 in it, given that I ace my other subjects? I am pretty confident that if I devote most of my time to my other subjects, I can get band 6s for 3U and 4U and Chinese. But then...

For my school in 2021, the number of band 6s were: English Advanced: 9 Maths ext 2: 8 Maths ext 1: 16 Physics: 4 Chinese continuers: 4

My school is ranked around 200th in NSW My internal ranks are: English advanced: 26/47 Mathematics Extension 1: 1/30 Mathematics Extension 2: 4/7 Physics: 3/30 Chinese Continuers: 1/8 My English really is just average (below average probably), I got a raw mark of 70/100 for trials For trials...
