Physics: Post your doubts here!

[ThePacifics]

if anyone here gave physics paper 41 then I wanted to confirm whats the proper answer to that iron core and aluminium foil jumping upwards answer?

 

[Kanekii]

Anyone has any good resources for "Momentum" and "Errors and Uncertainties" physics As

GUYS , IN THE SHM QUESTION ABOUT THE TROLLEY, WE WERE ASKED TO STATE AND EXPLAIN THE TYPE OF DAMPING IN THE TROLLEY.. HOWEVER, I DONT THINK I READ THE QUESTION PROPERLY .. I HEARD THAT IT SAID " STATE AND EXPLAIN " .. WHILE I ONLY STATED THE ANSWER AS '' LIGHTLY DAMPED ''.. WILL I GET A MARK..
I AM WORRIED BECAUSE WHAT IF THE MS IS SOMETHING LIKE THIS :
energy dissipates gradually with time M1
so lightly damped A1
I WON'T GET A SCORE IF IT IS LIKE THIS BECAUSE I WONT HAVE EARNED M1 ...

Does anyone know about confidential of Paper 33?

 

[Parhaakoo]

Does anyone know what happens if ur unable to complete the paper for some reason? My friend got unwell in p4 and she had attempted first 3-4 questions only. She wrote a report instead. Her expected grade is A*. Is there a chance she can still score A* if she does really well in other 4 papers?

well there were two marks so idk
i dont think so

 

[Zaki ali asghar]

there were two marks and then 3 for the explanation abt energy loss?

yh
i wrote abt friction tho
like between tyres and the floor

 

[Tauqir_hamed]

so i won't get a mark ? :/

 

[anastasia grey113]

youll get 1 cuz u dint answer the second part of the question

Any predictions for the Physics practical on tuesday? For those appearing in variant 33.

I like how youre worried over 1 mark and then theres me who fkd up the whole freaking q1 (which was quite easy, yes ik) and still chilling out xD

Yeah it's gonna be about a pendulum experiment and an electric circuit....that's what my teacher told me after she got the materials.

what sort of electricity experiment will be coming???
Any chance of posting the materials???

Nah, unfortunately, we couldn't see materials for phy... I only saw for bio (34) but it's going to be typical i guess....just go through the marking scheme of the years which has a circuit and pendulum questions and ur good to go

Is there any particular reason why the physics winter 14 varient 3 components had very very high thresholds. Paper 43, for instance, had a minimum of 67 for an A. I found it a bit tougher than summer 18 42. Not only paper 4, all the other components' threshold were very high. Hope 2018's wont be similar to that one.

Oct/nov exams usually have higher gt as compared to may/june and I believe that's because fewer students appear in oct than in may...

It wont certainly be 67 for 42, will it ? XD

Oh godd lets hope not xD cos paper was easy but i made alotttt of silly mistakes ugh
