Guys, I need some help in this paper:
http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Physics (9702)/9702_w08_qp_4.pdf
Q 1 b)i)
judging from the fact that you asnwered part A, you know its a sinusoidal stationary wave and X has same amplitude as Y. But at any instant they are moving in opposite direction so they're 180 degrees out of phase.
pd is 2.7 because V = V(total) x resistance (thermistor) / resistance (total) = 4.5 x 1800 / (1200+1800) = 2.7 this is a potential divider.9702_w05_qp_2.pdf Can anyone help me with 7 (b) (ii) 1. Why is the pd 2.70? galvanometer reading would be zero not voltmeter?
answer is E, because parallel circuits. so V across the 5ohm 3ohm line is 3V.View attachment 32315
q7 guys!
Hey, I have my physics practical resit tomorrow... And just wasn't sure about which setting you're supposed to have the voltmeter on (i.e 2, 20, 200?) and the ammeter aswell.... Can someone please explain which setting to have and in what circumstances? Thanks.
Oh ok then... Well in w11 n w12 they had electricity so it may not come this time... (It could still)... Just know how to plot graphs properly and learn all the limitations and improvements for mark schemes...They
The invigilators set the ammeters for you!
Any idea whats coming in tomorrows practical? Ive it too!

Nope..never... It will always be mechanics/thermal physics or electricityOkay! And btw has waves ever come in practical?
Okay! And btw has waves ever come in practical?
in the diagram V the final velocity is shown as the resultant of the two vectors that are added together and one of them is U inital velocity and the other is X so X must be ut in the diagram as v=u+atMay anyone please explain to me why the answer to question 7 (in the paper linked) is C?

nearest mm doesn't mean the table has to be in mm. eg. 0.582m is to the neariest mm because 0.582m =582mmIn part d why do we have to make the table of d im mm according to marking scheme though the ans we got in c(ii) is in metre?View attachment 32332 View attachment 32334
