Physics: Post your doubts here!

[Abdul Rahman]

i don't know anything about edexcel .. i didn't have a choice so i never explored .. i guess self study is the worst thing to do with a levels .. and that wasnt a choice i made for myself either .. i don't have a teacher LOL .. get a trained person to help you out .. people get As all the time .. it isn't impossible.

What do u mean , u dont have a teacher ? u dont go to school?

 

[Abdul Rahman]

self confidence is what you need bro....if you've worked hard, then leave the rest to Allah. He is the best judge don't curse CIE be strong withing yourself...inshAllah youll do good! Give it ur best shot...

Thanks for that bro , really need it.

no, im enrolled in one but because of personal problems i just cant attend school. i have to travel a lot and can't keep up and stuff like that most of the time ..
im just not the luckiest girl when it comes to a stable lifestyle.
but im hoping tomorrows gonna be good . inshAllah ..

Oh shit , where do u like live?
and yeah dw it will be good , if not dont panic just relax , people become successful without exams aswell.

isn't the wavelength 60cm as calculated before? :S

that wuz when there was 3/4 of a wavelengh in da tube... itsnot related to hear 1st loud sound u need 1 antinode in da tube which is 1/4 lamda nd u get a new lamda

Taking out my frustration is useless?

How do we resolve vectors??can anyone help please?

Any guess papers?

first here is how you convert the degrees and radians...
radians to degrees : multiply by 180/π
degrees to radians: multiply by π/180

Phase difference is simply is the fraction of the cycle (the angle) by which one wave moves behind the other.
you can calculate is by using this equation: (with degrees)
360 (x/λ) where x is the difference in the distance between the two waves...
or 360(t/T) where the waves are out of step by time t.
use 2π for radians, since 360 = 2π

For coherent waves....they have a constant phase difference...this is usually the case with waves fron the same source. It does not matter whether the waves are in phase ....but coherent waves must have a constant phase difference...which means that the difference between them is the same throughout. They must also have the same wavelength and the same frequency.
this is quite brief..but hope it helps.[/quot
thnks fr the phase difference

what is a closed triangle needed for equilibrium ?? same as the vector resolution triangle or not ?

ANYONE HAVE REVISION SHEET OF THE PRACTICALS???

Hey ya,

second attempt at AS Physics tomorrow.... :/

And I'm in Year 13. Do you guys know if I can still resit this AS Physics exam even when I'm not going to school anymore? because I'm pretty sure that I'm gonna mess it up tomorrow....

Physics is my life and I love it. Only problem is that my grades are not good at school because these CIE exams are so weird. They also sometimes ask stuff which is totally unneccessary to study Physics at Uni and they only do it to make CIE more sophisticated and only Top students who learn EVERYTHING possible are gonna get top marks ....

But yeah back to my question: Is it possible to resit it when you're not going to school anymore (ie between school and uni)?

How?

we got the stess 9.1 *10^8.so stress=force/area.u will get the area of the rod.then subtract the cross sectional area with the area of the rod

How ws Physics P2 guys?

It was simple but lenghty . The duration wasnt enough but it went awesome
