How were we supposed to calculate power?

P= Current square x Resistance of two wires.

P= Current square x Resistance of two wires.

I used the same formula.. but how two wires? How do we know that there are two wires? I simply used I^2 x resistance of one wire, will I get any mark?

there were two wires, From the two terminals of the battery.
You used the formula right, so you'll get a mark for that. Mark for the answer would be deducted.

gt will be around 37

 

[Muhammad TAimoor]

gt will be around 37

Even lower, I hope

 

[mnotanerd]

how was it?wt do u expect the GT ?wasnt it hard than may june?

what was the gt in may june 2013??

 

[Dashing Khan]

yooo guys wat was the amplitude...???

 

[rabos1]

what was the gt in may june 2013??

39 was A and 35 was B.

 

[rabos1]

yooo guys wat was the amplitude...???

How did you calculate it? I wrote 5 mm.

 

[mnotanerd]

39 was A and 35 was B.

can u send me the link to the gt?

 

[Dashing Khan]

yeah man i really hope the GT is really really low...

 

[rabos1]

can u send me the link to the gt?

Just search on google.. you'll get it.

 

[Dashing Khan]

how did ya know it was 5mm...??nd i dont think dat we had a calculation cuz it was jst 1 mark...i took frequency nd calculated Intensity nd with the relation I=ka^2 calculated amplitude...dont remember the ans...

How did you find intensity? K value? I think we should relax and focus on paper 1 now.. I made A lot of mistakes. I hope percentile will save all us. Gt should be 35

 

[Tirtho Sarker]

did anyone get power=41w and pq =.18m

yes..btw what was your distance in the cro question? mine was 360 :/

 

[Tirtho Sarker]

I used the same formula.. but how two wires? How do we know that there are two wires? I simply used I^2 x resistance of one wire, will I get any mark?

for the formula you will get 1.

 

[rabos1]

yes..btw what was your distance in the cro question? mine was 360 :/

Wow!! You were able to solve 2nd question

 

[DumbIdiot]

yes..btw what was your distance in the cro question? mine was 360 :/

i got 120m

 

[Tirtho Sarker]

Wow!! You were able to solve 2nd question

yes though the answers different for everyone.

 

[Kodzzz]

How did you calculate it? I wrote 5 mm.

i think it was 40mm
