AS Physics P2 !

[heavensown]

i had variant 21 .. it was good

 

[jose machado]

heaven dude did u goy 8 aand 1/8 ???? AND TELL ME ALL UOUR ASWNESRS DSSDS

 

[A star]

44.1

u guys are not allowed to discuss the answers why doesnt everone understand this rule for peace sake -_-

 

[jose machado]

WHY NOT

 

[A star]

its the rule of XPX SalmanPakRocks please explain

 

[Saadman]

i thi

What is the correct scale!? And do we have to mention the scale we took!? :O I just labelled my axes!

 

[Your-Blood]

Guys please don't discuss the paper before 24 hours.
It's just gonna make the percentile go up by letting others know that what questions were in exam.

 

[Ahmed Khalel]

LI did that way....not sure if correct though..btw what did you get for the length of the string??

ill tell you when the 24 hours finish, you know the rule "sorry"

 

[Malik777]

Was that wave was at 180* Phase difference? I mean It was like the ful stationary wave #3marks/22

 

[meobunny]

Insha Allah to na bolo atleast : O 55-56 grade threshold pe, u guys did great oh A* ajaye ga, atleast bakyon kmtoh buray nahi ayen ge itnay ! :/

 

[Beaconite007]

In Sha Allah the gt won't exceed 40.
(For P22)

Okay since 24 hours are up,
The graphs were easy. The first one was the same as the force-time one. Just that accelaration was on 3. something. The second one was a right angle triangle. Starting from 0 to 16.8. And then dropping vertically at 2 seconds.
These are absolutely the right graphs

The second graph didn't drop vertically after 2 seconds. The question didn't mention anything about frictional forces, so I assumed it would carry on with the same velocity, hence it would be a straight horizontal line.
Those are my 2 cents

for the first graph, i connected the first and last point to give me a downward slope (diagonal-deceleration)...was that wrong? i didnt have time to do the 2nd!

and what was the stationary wave question?? how is it drawn? i drew a straight line through the origin ....

Yeah, I drew a straight horizontal line too.
Didn't know what I was doing

ah okay not just me...coincidence was..yesterday morning before the exam, i asked my teacher about a similar question (M/J 2011 P.23) , where we need to draw a stationary wave on top of the other and T is 0.25....he told me its a straight line but i have no idea why. So when i sow the exam qq, i just decided i would do that rather than leaving it empty...hopefully it's right...coz i know am losing the whole 9 marks on the graph questions!

lol, our teacher gave us that paper for our mocks exam

 

[Nerd for Word]

what was the answer for the change in momentum for graph 2??!!! what do you guys expect the grade threshold to be??!!!

LOL my teacher made up his own paper for my mock (i was alone coz i had to pospond) and let me tell u, he must have been so angry that he's doing three versions of the mock, that he decided to put all the hard questions in mine. I simply got a D for mock coz i gave in my mock half empty. Gotta say..the external was way easier (not counting the graph question) hahahaaa

I have no idea, i didnt have time to answer..but am hoping the threshold would be..in mid 30's....if less then better
