avoid using abusive words such as fag again. if you solved and he didn't get then it doesn't mean you will get rude to him. and the way you explained no one would get it. read the terms and rules of this forum: https://www.xtremepapers.com/community/help/termsI just did fag -_-
please explain him that question in which i tagged you then i will answer your doubt.
in 1/4 cycle antinode gets from highest point to zero. then in 1/4 it gets to lowest point then in 1/4 it gets to zero. then in 1/4 it gets back to max. so in one T it completes on cycle.new wave will be straight line.
Haya Ahmed please give him the pictures and animation which i gave you yesterday and explain it to him how i explained it to you. i have to solve many other doubts.
energy is directly proportional to square of extension. if E is half, then extension is 1/√2 of max extension = 2.6/√2 = 1.84http://papers.xtremepapers.com/CIE/...nd AS Level/Physics (9702)/9702_w10_qp_23.pdf
Q5 c)ii) ?????????????????? Plz Suchal Riaz
Done .. now answer 2b ASAP ! :/please explain him that question in which i tagged you then i will answer your doubt.

guys how are we suppose to do q 5part b iii i dont get how we r suppose to draw the new wave
by conservation of energy the height of mass will be the same.Done .. now answer 2b ASAP ! :/
current = charge/timeOkay here's a questio!
A beam of alpha particles produces a current of 1.5 pA. Calculate the number of alpha particles per second passing a point in the beam. And please explain as well
idk the 2013 papers were easy as well as P1 of this year. but chemistry was different. and mechanics was difficult too. but i still hope it is easy.Suchal Riaz do you think tomorrow's exam will be hard? and i am sorry for cussing
post link. everyone posts link to get their question answered.Heeyy guys can anyone lemme noe how to solve oct nov 5 question 3.c...Please..
I think you are wrong. charge of an alpha particle is +2 not +4!!!!!!!!!!!!!!!!!!!current = charge/time
charge of an alpha particle = +4e
number of alph particle = n
total charge = n4e
current = 1.5 x 10 -12
so 1.5 x 10 -12 = 4ne/1 second
n=(1.5 x 10 -12)/4e = (1.5 x 10 -12)/4(1.6x10 -19) = 2.34 X 10 6
