Physics paper 31 , (a death call)

[sma786]

guyz what was the max speed? :\
was it 7. something???
please discuss the paper !!

 

[yuyu_373]

variant 2??

 

[sma786]

variant 1 !

That's what i got 7.777777778=7.78m/s

 

[sma786]

That's what i got 7.777777778=7.78m/s

yeah okay me too, thats good then

 

[areebaization]

what abt the LDR position? anybody who had time to use their brains in the last Q? :/

 

[svenas]

yeah okay me too, thats good then

I wrote it as 9.3 m/s

what abt the LDR position? anybody who had time to use their brains in the last Q? :/

yeah lol, LDR was in A i guess ..

I wrote it as 9.3 m/s

u found the accelration , v had to find the speed

 

[areebaization]

yeah lol, LDR was in A i guess ..

I wrote that too!

I wrote it as 9.3 m/s

Did u take the distance as the steep line's height or something?
Coz for the speed we had to directly choose values from the graph of the distance and time..

i got 9.3333333

oh yes, i had plenty of tym

 

[areebaization]

oh yes, i had plenty of tym

haha what's ur answer then

 

[svenas]

oh yes, i had plenty of tym

Hi....how u did?
Also tell me wat u wrote for the question about pistons why distance moved...?

da LDR shud b in da lower gap

 

[IGCSE O/L student]

haha what's ur answer then

it shud b in da lower gap

Hi....how u did?
Also tell me wat u wrote for the question about pistons why distance moved...?

hi! it ws fyn, alhamdulillah!
da one which moved a small dist is b'coz da area ws big. da other one coz da area ws small

 

[sma786]

the direction of the current was to the right?

 

[IGCSE O/L student]

the direction of the current was to the right?

wat current?

 

[svenas]

da one which moved a small dist is b'coz da area ws big. da other one coz da area ws small

this i wrote in the first part when they asked abouy the force...but for this i wrote about work done force is inversely proportional to distance...wat u thnk?

 

[sma786]

wat current?

the current in the wire PQ ..
