physics paper 1,2 ........can we discuus da papper nw?

[plantaholic]

sometimes CIE gets lame too!
so hope for the best...

right! May Allah give us all good grades. Aameen!

Anyone remember the 2 mark part above or below this temperature question in sec B question 1??

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?

 

[pakisatan123]

the wave form question. in which point x was marked and we had to describe wave motion etc

dont we had to draw a line from x till two more waves

 

[bikermicefrmars]

yeah twelveoclock is right..? What was ur answer to it?

 

[plantaholic]

i wrote keep external condition right is my right

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?

 

[plantaholic]

ye

dont we had to draw a line from x till two more waves

s because one wave took o.5 secs and we had to draw for one sec

 

[pakisatan123]

replyy

 

[plantaholic]

there w

think it was WHY? the temperature should be kept constant.

as also a part abt how 1 complete set of readings could be taken. what did you people write?

 

[plantaholic]

replyy

just did! yes it was two waves

 

[pakisatan123]

ye
s because one wave took o.5 secs and we had to draw for one sec

but whats up down thing plzz tell worried

 

[pakisatan123]

there w
as also a part abt how 1 complete set of readings could be taken. what did you people write?

keep voltage current same and keep wire of differnet lenght and take resistance

 

[plantaholic]

but whats up down thing plzz tell worried

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?

 

[plantaholic]

keep voltage current same and keep wire of differnet lenght and take resistance

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...

 

[plantaholic]

in the resistors question, what was the total resistance of x y z?

 

[pakisatan123]

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

 

[asd]

keep voltage current same and keep wire of differnet lenght and take resistance

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.
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.

i think one mark each...

in the resistors question, what was the total resistance of x y z?

1/20 + 1/30 = 3/20 = 1/R
R= 20/3
Total resistance = 20/3 + 10 = 50/3 ohms

i wrote keep the conditions which were used previously same
