Yeah, If you dont get no Astar Ill unfollow you.Gud Luk to u too A star
go ace the exam
Oh wait, there is no A star in AS :|

Q1b) Apparently the units cancel out? How the hell..?
they do work them outhttp://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Physics (9702)/9702_s12_qp_21.pdf

lmfao :O asd u better do it nowYeah, If you dont get no Astar Ill unfollow you.

Now that was totally randomWhy does the small rain drop reach terminal velocity faster than a larger rain drop ? please give a detailed explanation thank you
Why does the small rain drop reach terminal velocity faster than a larger rain drop ? please give a detailed explanation thank you
but the surface area exposed will also be less so air resistance will take more time to bring the drop to its terminal velocity.. nahi?Now that was totally random
Okay, so I guess cause the smaller drop has less weight, so the force required by the air resistance to counter the weight is obv smaller now. It will take less time.
link?Guys what about June 2002 on waves, (b.) part where it is a laser being diffracted in grating and made an angle of 162 and 136 degrees thing, I don't get it at all =(
whts the doubt? its an easy quest I jus did it now if I can help I willGuys what about June 2002 on waves, (b.) part where it is a laser being diffracted in grating and made an angle of 162 and 136 degrees thing, I don't get it at all =(
link?
It's not there in the xtremepapers site, can you upload it here? I have it in my desktop a classified one
whts the doubt? its an easy quest I jus did it now if I can help I will
in diffraction grating its always a rule to divide angle by 2 in other questions of this type we r always given a single angle but here we r given side angles n we need to get the angle in between so 162-136=26 then 26/2=13 n then the usual way dsin(teta)=n(lambda)Can you explain me what are those angles? And why theta would be (1/2)(162-136)?

they have given it the other way round in the mark scheme7(b) the mark scheme said theta= (1/2)(162-136), why?
why is it wht? tell me ur doubt clearly so I cn xplain bttrBut why is it then? Why the rule is like that =( ?
