where can i get them from?
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!

answer is A can anyone explain how
Well its a velocity-time graph and a sine curve. To get displacement from velocity, u have to do the integration of velocity which implies the integration of sine here. Integration of sine gives negative cosine. Therefore the answer will be an inverted cosine curve. Therefore A. Hope it helps.answer is A can anyone explain how
one thing what has sine to do with velocity and cos with displacement?? are they relatedWell its a velocity-time graph and a sine curve.

Well not really... but there are many cases in the chapter wave where the velocity of a particle moves sinusoidal (related to the sine curve).one thing what has sine to do with velocity and cos with displacement?? are they related
Hi everyone
Can anyone tell me the differences between STRONG , STIFF , RIGID and TOUGH according to young's modulus ??
Can't find rigid though. Hope you can understand....

there isn't any for nov 09, jun 10 and nov 10 alsoDO YOU HAVE THE ANSWERS FOR THE PHYSICS COMPILED PAPER 1
hello could you help me with no 1...thanks
1(a) Distance is scalar, it only has magnitude, no direction. Displacement is a vector, it has magnitude and direction.
(b) Check your books it's about inertia.
(c) I don't know if you can answer like this... Since velocity is constant, acceleration is zero. As acceleration is zero, resultant force is zero. Tanker in equilibrium when there's no resultant force on it.
Resultant force balanced out by drag force on water?
thanks I needed to know about the vector diagram and the calculation part after that
The number of molecules per cubic metre of air at standard temperature and pressure is about 2.7 x 10 ^ 25 m ^-3 .
What is the average separation of these molecules ?
ANSWER : 3.3 x 10 ^ -9
Thanks in advance
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.
