How was the paper??
Grade thresholds?

 

[sandman za]

no ways 55, why not have 35 there? gt usually 30-40something out of 60

 

[Bba321]

Yah I think 30 something too! I think I messesd up electricty

 

[hassan.arif.12]

how to find the resistance in that electricity question

 

[Mujtaba Ali]

what was the resistance of resistor X? 4?

 

[PlutoHuman]

Usually for Oct/Nov the grade tresholds are lower........I mean lower than 40...but this paper was kind of, and I repeat, KIND OF easy

 

[Sebastien220795]

what was the resistance of resistor X? 4?

i got 4 aswell for resistance of X

 

[hassan.arif.12]

i got it 6.. i know its wrong how did u guys get it as 4??

 

[Bba321]

I got 4 too

 

[hassan.arif.12]

i got 4 aswell for resistance of X

how??

 

[Amjad khan]

what was your equation for the Kirchhoff law for the first circuit and for second as well?

 

[Sehrish Ahmad]

Paper Alhamdulillah went good
yup resistance of X I got 4 too...
Well I did sm careless mistakes aswell :l like what was ur value for kinetic n potential energy ?
Overall ppr was easy but I still cannot believe this grade threshold like losing 20 marks even gives u an A is this seriously possible?

 

[abdulkhan]

what were the equations for Kirchhoffs laws both parts and reason for current not to increase 4 times

 

[maq1996]

what was the height in that projectile question? 5.4?

 

[abdulkhan]

what was the height in that projectile question? 5.4?

1.8m

 

[maq1996]

oh shit... well I hope they award ecf marks, cause one other part was related to it.

 

[Bba321]

How did you find the height and max kinetic energy?

 

[Yousif Ahmed]

good morning guys
for the electricity part, i got the resistance X = 3.11
& The max height = 2.75 m
so is my ans are correct?

 

[Ahmedlool]

did you guys get for the longitudinal and transverse wave similarities that they can both be diffracted

 

[PlutoHuman]

what was the height in that projectile question? 5.4?

At maximum height, all of the kinetic energy is converted to potential energy.......this is also the law of conservation of energy.
So u can also check with that....if ur maximum kinetic energy equals ur maximum potential energy then your answer would be correct.
But for me the maximum height was 1.77 and the KE and PE both were 11.3
