How did Physics P-22 go?

[Faiqa Ahmad]

Hi how was the paper for you?
What do you expect from P-1 and the practical now?

 

[Amandaissocoollike]

There's no way it'll be higher than 45. GT is always low for physics.

Can u tell what is cuming in 32 phy chem practical

How can we tell you when it hasn't even been done yet lol

How many marks do you need for a C in this paper? Im going to get about 15 marks on this paper

same here i think maybe if we do well in the MCQs and practical we can manage a B overall, somehow. i cant believe i messed up almost my entire paper

15 marks is a U right? Btw what did you get for your momentum change?

Idk i think its a D? not sure. Dude dont even ask, i got 8 x 10^ something, i dont know what i did

Guys i used the Kirchoff's second law for the Resistance of X and i showed them the whole long loop.. But during exam i got a different answer and at home i got 4500. My signs and the loop is on point so i do get 2 marks out of 3 right?

Check this question , in old past
paper , and check it marking scheme

 

[rabia10]

r-4500

 

[rabia10]

any idea about the instruemnts used in ur centre?

 

[AbdullahBShakeel]

Guys i know the answer is 4500 i meant i used the Kirchoffs second law and the method is on point.. Just the answer wrong so i get 2/3 right?

Did you get 4500 on the paper?If not then you wont gain marks

No but i did show correct working :/

Wouldnt the correct working have shown the correct answer.Kirchoffs laws had nothing to do in this question even,the hint was already given that we had to compare powers transformed.

Nah Kirchoffs law was the correct way. The only thing what i did wrong was i didnt put the =0 sign in my calculator. So my calculator messed it up.. At home i did it again and it was coming as 4500. Try it yourself. 5.33x10^-4 x X + 5.33x10^-4 x 15000 + 5.33x10^-4 x 3000 - 12 =0. Look what the answer is.

I got 4500 too.

Guys.... in question number 2.. for finding distance travelled by the stone in one part I messed up and used the value of velocity instead of gravity by mistake.... so my answer came 23m......thus my answer for displacement came -7.66m..... how much mark will i lose for this..?
and for finding the frequency in the stationary wave again by mistake i divided the speed by 2.0 cm instead of 2.8cm.... so my answer came 15GHz instead of 10.7GHz.... how much mark am I going to lose for this??

I feel like kicking myself.!!!
