We know that frictional force always acts along the plane. Never at an angle to it. Therefore the frictional force acts along the line AB. Since we know
Work done= Force x distance. The distance AB is found by using 4.1/sin30. Hope it helps
S11 23:
Since the wave is a stationary wave all particles between 2 nodes are in phase. Since X abd Y are in phase the phase difference is 0 (as they are between 2 nodes)
Hope it helps you
cheers

Q7 (b) i= Correct answer is I3=I2+I1
But ain't I3 entering a point too (at Y)? :-s

in qs 4b(iv) the 3rd part my calculations are dis what is wrong: V=IR, 2.1-0.24*1.8=0.432V
http://www.xtremepapers.com/papers/CIE/Cambridge International A and AS Level/Physics (9702)/9702_w11_qp_23.pdfthere is no 4b(iv)
