It says "collide elastically" therefore kinetic energy(K.E) before collision is equal to kinetic energy(K.E) after collision
need more understanding of elastic collisions?? 
It's related to viscosity? Was any of you guys made to study this?
so far we haven't learnt anything of that sort yetDo we have stoke's law in our syllabus?
are you talking about As or A2?Do we have stoke's law in our syllabus?
AS. Apologies for not being precise.
we haven't studied it and we are done with forces in our school but i do think its there for A2
Under the topic of equ of motions and kinematics .
IF the velocities are in same direction or in opposite direction then the velocities are added otherwise they are subtracted thats why before collision they are moving towards each other and after collision they are moving opposite to each other so the velocities are added and then the ans is A.
stoke's law is not in AS syllabus.Do we have stoke's law in our syllabus?
Pacific phy 1 and 2 ...for AS these books are v.v.good and you can also try long man if u want to ...
I am using OCR, understanding Physics ,the coursebook and bath physics
and the best 1 is?
the coursebook
ZaqZainab it's actually a book for 4k. I don't wonna waste that. Do you second what Hassan Ali Abid said?
4k? you can get a photocopy and its worth it dude
even I don't know him. he's a member who replied to my query. i quoted his reply.
and i asked for your opinion on this
i edited my last reply i am sorry i did not see the name of the guy beforeeven I don't know him. he's a member who replied to my query. i quoted his reply.
and i asked for your opinion on this
when the size of the slit(hole) increases so more light will pass and the bright regions will become brighter and the fringe separation will remain constant and also the dark areas will remain as darker regions ( no change in them)
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
