All what u have to do is 0.3/t=0.01
Find t=30 s
so give and estimate of number of oscillations in 30 s....
simple
Hey friend i can't still understand it . Could you elaborate please please please
Thank you.
Can anyone pls upload may/june 2012 paper 2 with the answer sheet pls?
AFAIK, they can also produce destructive interference.do coherent waves only produce constructive intereference ?
what help do u need??Someone please help me for june 2007 p2 no. 1![]()
for the no. 1what help do u need??
what help do u need??
A bit confusing for meUse a compass set mark out angles 40 degrees for 20 then 40 for the appropriate angle from the graph n cntinues until 80
A bit confusing for me![]()
And for the (a)(ii) ?Confused abt ??.. u knw hw to use a protactor...so refer to the graph at 20 x 10^-3 the angle is 40 degree so using the protactor find the postion for 20 x 10^-3 in the meter ??
And for the (a)(ii) ?
Thank you very much ! You are a genius !See ranging from 20 to 40 difference is 40 degree then frm 40 to 60 is 70 degree...frm 60 to 80 is 90 degree .....what u observ is the difference between the angle isis approximately 2/3 . e.g(70-40=30) and 90-70=20 (2/3 of 30) then 102-90=12 (approximatel 2/3 of 20) therfore whn v= 100 x 10^-3(1.0x10^-5)... the increment is 2/3 of 12 = 8..hence postion for 1.0 x 10^-3 is equal to 102 + 8= 110 degree..refer to markscheme the ans is between 107 and 113 so any doubt in the ans ??
Thank you very much ! You are a genius ![/quThank you very much ! You are a genius !
