right! May Allah give us all good grades. Aameen!sometimes CIE gets lame too!
so hope for the best...

think it was WHY? the temperature should be kept constant.Anyone remember the 2 mark part above or below this temperature question in sec B question 1??
which question?Anyone remember the 2 mark part above or below this temperature question in sec B question 1??
dont we had to draw a line from x till two more wavesthe wave form question. in which point x was marked and we had to describe wave motion etc
i wrote that too k keep physical conditions constant. i've no idea if its correct or not.. would any KNOWLEDGEABLE person let us know?i wrote keep external condition right is my right
s because one wave took o.5 secs and we had to draw for one secdont we had to draw a line from x till two more waves
replyydont we had to draw a line from x till two more waves
as also a part abt how 1 complete set of readings could be taken. what did you people write?think it was WHY? the temperature should be kept constant.
just did! yes it was two wavesreplyy
but whats up down thing plzz tell worriedye
s because one wave took o.5 secs and we had to draw for one sec
keep voltage current same and keep wire of differnet lenght and take resistancethere w
as also a part abt how 1 complete set of readings could be taken. what did you people write?
in the same wave ques we were asked to draw the direction of the movement of a wave particle at the crest. where x was marked.. do you remember it now?but whats up down thing plzz tell worried
i wrote k take one reading without the wire and find resistance of basic circuit components.. then take reading with wire.. repaet thrice to eliminate error...keep voltage current same and keep wire of differnet lenght and take resistance
i forgot to do that part i thought we only have to show x with two waves was these two parts of 1 mark replyyin the same wave ques we were asked to draw the direction of the movement of a wave particle at the crest. where x was marked.. do you remember it now?
Lol how can you keep current same when you change the length of wire? You increase the length of the wire, current itself decreases because resistance increases.keep voltage current same and keep wire of differnet lenght and take resistance
i think one mark each...i forgot to do that part i thought we only have to show x with two waves was these two parts of 1 mark replyy
1/20 + 1/30 = 3/20 = 1/Rin the resistors question, what was the total resistance of x y z?
i wrote keep the conditions which were used previously sameLol how can you keep current same when you change the length of wire? You increase the length of the wire, current itself decreases because resistance increases.
The correct answer was to Take the readings on ammeter and voltmeter for different lengths of wire and calculate the resistance using the equation "V=IR". Tabulate the results.
