Do you all know good websites for AS level physics.....
I need a good note of OSCILLATIONS AND WAVES MODULE......
So can anyone upload a good note for me please?

Check the physics module at https://www.xtremepapers.com/community/threads/final-revision-for-physics-and-chemistry.33891/

yaar. Unrelated but does anyone know if Physics Cambridge Endorsed Coursebook for A Level 2nd Edition is available in its Pirated Version? Lahore pls.
Thanks.

Q33 (Ans: A)(Also, are all three P Q and R parallel to each other)?

There are lots of ways for this question
I find V the easiest to use in an explanation
PQR all have same resistance
Q,R have same V while P has 2x of their V so 2V
Power = (V²)/R
so Power ratio of P Q R =((2v)²)/R: (V²)/R : (V^R)/R or 4:1:1
total power is 12, divided to 6 parts so Power of R is 2W

moment = force x distance
clockwise moment = anticlockwise moment
W x a + F x h = W x 2a

 

[Keirad]

moment = force x distance
clockwise moment = anticlockwise moment
W x a + F x h = W x 2a

But where is the pivot

So is P Q and R parallel to one another? I'm always having trouble deciding whether they are parallel or in series.. How to differentiate them?
