maybe its worthy to mention that initially scientists used electric field to deflect but the technology at that time was not accurate enough to detect the deflection

Hey guys! Just have a question about our cohort. Our physics teacher is bludging this year (he only gives photocopies of a textbook and literally just read it out) This results in our cohort are very bad. we have 13 ppl in our cohort and only 6 of us are studying. The rest literally handed in...

what raw mark would you guys reckon for a state rank? Is 69/70 possible? I was brain damaged during the exam I think, for the last mc I literally forgot horizontal line tests and vertical line tests rippppp

its a question from their additional sample questions, but i think the answer is wrong or i am totally retarded lol

https://docs.google.com/document/d/1G6GNbNLlYtp5NVdskTd-I4HnXWscSIZouT2hwF8aAw4/edit question 3 in this document, shouldnt the answer be A? As \frac{I1}{I2}=\frac{N2}{N1}

nice copy from matrix lol but u didn’t answer my question :’(

for the last question what I did was i) equalling the differentiations of the two functions (as they have a common tangent at x0) ii) consider squaring both side and use sin^{2}x+cos^{2}x=1 to convert into the square of sin are equal then we notice that x0-\alpha and x0 can't be positively equal...

Hey, I am doing physics past paper and I met a problem which is confusing me. this is from HSC 2018 question 19, basically its talking about on a bus, there is a ball hanging on it and what would happen to the ball if the string is cut and the bus suddenly stops. I understand the perspective...

I played leagues the night before exams and the feeling of angry because of trash team totally made me forget the anxiety of the exams LoL

terry lee got the temperature question wrong hahahah He didn’t find dT/dt lol

I legit got the same mistake and this is the only mistake I made lol. I had the same feeling and checked everything except “forms part of “

yeah it’s 5 I made a typo

i got \frac{324(\sqrt{2}+\sqrt{6})}{4} iirc

maybe coz i have a "inertia" of finding T usually LOL

i got 14 for the binomial one LOL maybe i made an arithmetic mistake the trap are 1) for the temperature question, its asking the rate of change ie. dT/dt not T lol 2) the motion question, its asking the first time when "speed" reaches half of the maximum "speed" so you gotta consider both...

lol there are so many traps wth

Hey Guys I love coming up with my own problems because I think this is a better way of learning. As 3u exams are approaching, I'd like to share the interesting questions that I made up during the year and put them into a "trial paper". There will be solutions and also I haven't finished...

for these type of questions, you just need "find z strategy". let z=x+iy, z^{2}=2-\sqrt(5)i and then expand, by equating the real parts and imaginary parts you should be able to get two equations about x and y now all you need to do is to solve simultaneously. try some exercise and hopefully...

Lol I barely studied for the motion parts, all I used is the mechanics knowledge from 4u. if someone can teach me what d(1/2 v^{2}) even does, that would be much appreciated.
