3(c)be more specific like paper and question part
?Accuracy and Precision?
can somebody tell me..a situation where resonance is useful and one where its is harmful....pls write a expplained sentence....
Aoa,http://www.xtremepapers.com/papers/CIE/Cambridge International A and AS Level/Physics (9702)/9702_w07_qp_4.pdf
Q11 a. why is a country divided into a number of cells?
There is no 11(a)(ii) !
there is Q11 a (ii) :S June 08 paper 4. http://www.xtremepapers.com/papers/CIE/Cambridge International A and AS Level/Physics (9702)/9702_s08_qp_4.pdfThere is no 11(a)(ii) !
if u r talking abt part (b) i would advise you to learn the answer frm the m.s
this question has been repeated many times!
Oh, ok!there is Q11 a (ii) :S June 08 paper 4. http://www.xtremepapers.com/papers/CIE/Cambridge International A and AS Level/Physics (9702)/9702_s08_qp_4.pdf
No, it isn't related to Centripetal force - you're not expected to know about it in an AS Level paper. B should be the answer, because that is the resultant of normal force and friction force on the tyre. Force of friction is in the same direction as car's motion because the tyre must be rotating in a clockwise direction.
aoajune 2002 q4b) at max displacement the p.e is maximum. and at mean position it is zero. so the graph will be at max at max displacement. but it will be all above xaxis because energy can not be negative.
c) t = 2pie * sqr root of mass / sqr root of 'k'
when mass decreases time period also decrease.
sorry i dont knw abt amplitude
What exactly am I supposed to write? :s do i write this all ^nov 2002) when 1/2 f0 is impressed then the time period will be 2T. so every impulse is after 2 oscillations. means alternate oscillations are energized. so there is continuous increase of amplitude at every impulse.
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.
