8 - Ans: D.
A man stands in a lift that is accelerating vertically downwards, as shown.



12 - Ans: B.
Two forces, each of magnitude F, act along the edges of a rectangular metal plate, as shown.


18 - Ans: B.
A trolley rolls along a horizontal surface and then travels up a slope before reaching a second horizontal surface.


29 - Ans: B.
A beam of laser light is directed towards a narrow slit. After emerging from the other side of the slit, the light then falls on a screen.


30 - Ans: C.
The diagrams show four pairs of waves. In each case the displacement y measured at a fixed point is plotted against time t.


36 - Ans: B.
Two cells, each with electromotive force (e.m.f.) E, but different internal resistances r1 and r2, are connected in series to a resistor R.


37 - Ans: C.
Three identical cells each have electromotive force (e.m.f.) E and negligible internal resistance.
