We are currently struggling to cover the operational costs of Xtremepapers, as a result we might have to shut this website down. Please donate if we have helped you and help make a difference in other students' lives!

that is because formula is MxGxHPhysics 9702/M/J/09....MAY JUNE 09 paper 1 question# 15....can please anyone tell me that why the answer to this MCQ is option B? The new height after water flows from X to Y would be h/2
.
A car travels one complete lap around a circular track at a constant speed of 120 km/hr. Determine the magnitude of the displacement of the car in a time of 1.0 minute. (The circumference of a circle is 2πR where R is the radius of the circle.)
does potential increase because of resistance as more work has to be done on the charge
This is an Edexcel question that I'm having trouble with. I'll write my answer and can someone please point out what's wrong with it (4 marks):
Newton's first law states than an object would continue with constant velocity or remain stationary if there;s no resultant force. When the train decelerates, there is a resultant force acting on each person in the direction that the train is travelling in. THis means that person A would fall and collide with person B as persons B and C would remain in their seats due to the fact that they have their backs on chairs which would absorb the force. Person A's motion is an example of a resultant force quoted in Newton's first law.
I'm pretty sure there's something wrong in there because not each point matches the mark scheme but that is how I would answer it, so does anyone know how they would go about correcting this?

I just can't seem to get the right answer
A particle moves with SHM (simple harmonic motion) of period 4 seconds and amplitude 4 metres. its displacement from the equilibrium position is x. find the time taken for it to travel -
a) from x= 4m to x= 3m
b) from x= -4m to x= 3m
Thank you very very much.

please can anyone help me with a link for topic wise pastpapers for p2 and p4??? thnks in advance
a)
Angular velocity=w= 1.5708 rad/s
Time it takes for quarter oscillation(ie from 0m to 4m)= 4/4 = 1s
or the technical way
x= xo sin(wt)4=4 sin(1.5708 * t)t = 1s
Time it takes to reach 3m from zero(starting position):
x= xo sin(wt)sin(1.5708*t) = 3/4t= 0.5399
therefore, time from 4m to 3m= 1-0.5399 = 0.46s
b) Time it takes from -4m to 3m = 1+ 0.5399 = 1.54s
Let me knw if u want a picture to help u visualize.

Hi everyone, AsSalamoAlaikum Wr Wb...
To get things organized in a better way, I am making this thread. As othewise, some queries remain unanswered!
So post your PHYSICS doubts in this thread. InshaAllah other people here will help me and you all.
NOTE: If any doubts in the pastpapers, please post the link! You can find links here!
Any Physics related notes and links will be added here in this post. Feel free to provide the links to your notes around the forum, or any other websites!
Thanks!
Jazak Allah Khair!

Did i get the correct answer??Thank you so much!
It helped a lot.
Bro al the papers r on xtremepapers... which paper cant u find???Hi,
Do u have alll the past papers for 2012(June and Nov) PHYSICS? I can't find some 2012 on this site.
Also I need further maths (all modules including mechanics) and Maths and CHEMISTRY.
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
