thanks, got it4 nucelon number
2 proton number +2 nuceleon number=4 nucelon number

thanks, got it4 nucelon number

well didnt find this in the book.is tht a physics - related term, or just generalized??
thanks, got it
okay c for findind out the force u need to know the formluae f=change in p/change in t(p means momentum)http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Physics (9702)/9702_s12_qp_21.pdf
Question 1, b(i) why did they add to velocity 19 ?
lol thankss, i got it already they took 19 because thats the velocity when the ball was hitting the groundokay c for findind out the force u need to know the formluae f=change in p/change in t(p means momentum)
so the change in p is 0.0465(18.6+19)/(12.5/1000)
not aware of calculations but..it is the point of time when the mass just starts to decelerate after that point.... see the gradient.http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Physics (9702)/9702_s12_qp_21.pdf
Question 3, b(i), why would the speed be max when the y=0 on the graph because the speed is 0 then if we use the formula s=d/t
and it is max only when the t=0.4, thats when the speed is 10ms^-1 ?!
got it!not aware of calculations but..it is the point of time when the mass just starts to decelerate after that point.... see the gradient.
http://way2science.com/lamis-theorem/Someone kindly tell me abt Laami's Theorem.
c(i) or (ii)?http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Physics (9702)/9702_s12_qp_21.pdf
Question 3, c(i)
why did they take x = 15 ? shouldnt it be 35?
ic(i) or (ii)?
Is answer 1.7?Paper 2 -oct/nov
Q5 (a) part 2 ? hw were suppose to calculate current :/
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.
