What was the load unload graphs answer?

Definitely A. I chose D. But for sure it was A after discussions.

 

[Zaki ali asghar]

one of the momentum questions was repeated in which there was something like m1gh1 type ans was B

 

[Zaki ali asghar]

Yep the load unload was A.you had to either subtract larger triangle area-smaller area or the trapzeium area

 

[shahzaib ihsan]

now 6 wrong.\.. gg

 

[Zaki ali asghar]

The repeats i remember so far Q2 the one about resultant force,the mircrometer one,the graph of what does x and y represent,the momentum change,the new deflection of electron,the scale one right below the forces in circle Q,the resistance one which had a factor of 16.

Just came back from my 9702 paper 11 exam, and Alhamdulilah it was really good

P12 There was a question with the frequency orders. What was the answer to that? Did it include the visible light as 6 x10^?
Somthing?

B: micro infra visible (left to right) the third was visible first was micro, micro being the one with lowest frequency and visible light with highest frequency. I personally did it via wavelengths I converted frequencies to wavelengths by dividing 3 x 10^8 (the speed) by the frequency to get wavelength and then compare since I memorized wavelengths.

That was B for sure coz was one the order was 0.0.1m which is for microwaves

Guys, May Allah Give us all excellent marks Insha Allah. Salam Alaikum Guys. I hope to meet you guys next year Insha Allah. Do keep us ALL in your prayers!

 

[Thought blocker]

I hope u all get A

"That q about sqrtmgh was C, the sum of m sqrt 2gh1 and m sqrt 2gh2"
and "the The one about air resistance was C, the scary looking equations. I got it wrong"

How can they be C?

the question about momentum in which there was underoot mgh1 and h2,the answer was B.Check up O/N P13 Q11

Yeah whatever it was lol but was m(sqrt2gh1 + sqrt2gh2) right?

 

[Holmes]

10 revolutions in 1 second
50 teeth in 1 revolution
1 teeth = 1 Hz for that metal strip thing
50 x 1 = 50 Hz in one revolution if one revolution per second
10 x 50 = 500 Hz in ten revolutions if ten revolutions per second

v = f x wavelength
330 was v
330/500 = 0.66m

Thank God I got it right. I was stuck in A and i think B

now 6 wrong.\.. gg

oh yes same going on with me.

 

[anastasia grey113]

Oh darn. Many others ik found it to be difficult and awkward too. Shouldnt be more than 30 for an A. And overall physics is lower than others like chem and bio so dont worry if your other phy papers went well.

lol dint read this Metallic9896
i think v both r in the same boat with many others
i knew everything n idk what just happened to me
i read this thread n now i feel like i lost 9
cant get more than 31 now :/

 

[nishant sapkota 123]

hello guys.In overall grade threshold we r supposed to get specified mark for corresponding grade in 130 or 140 in physics????????

lol yeah it kinda is embarrassing on a personal level when you get 38 ish in practice past papers and then something like this happens. But no worries now what's done is done. XD

lol true
what u doing now btw now that u r finally done with AS?

 

[Metallic9896]

lol true

Haha, not AS, A2 XD but not free yet cause going to med school, so stuck in prep for entry tests and the like. I'm also working on/thinking about making a website to dump in my O/AS/A2 level notes/advice/tips/answers to questions, all in one place, to pay back to the internet for all that it gave me when I needed it most. Will share it here with y'all if I manage to go through with it.

What you up to? AS done?
