Shortly

astarmathsandphysics:
I dont habve o/n 2001 p1
mj 02
q2. B cos x+-y=z
15.d cos resulta of 3 and 4 is 5 to upper right
26. 1 period=4 squares =4*2ms=8ms
1/8ms=125Hz B
28. path difference =1/2 wavelength C
35.resistance in ratio of voltages accros resistance 2:1:2 C

ruby92:
2.why not A? how do we know the direction of the resultant force?
could you please explain Q's 15 and 35 in more detail

Also o/n 2002 paper 1; 36

halosh92:
could someone explain q3b
i dont get it , dont we have to use the fdsin thita formula here..shouldnt the distance be perpendicular to the force..
in the ms..they multiplied the distance (in the direction of X) by X
??????????????????URGENT
thx
