- 1(a)(i)Explain why this is not the best way to support the rod.1 mark
- 1(a)(ii)On Fig. 1.1 sketch a better orientation of the stand, boss and clamp to support the heavy rod.1 mark
- 1(b)(i)Draw how a metre rule and two set-squares can check that the rod is horizontal.1 mark
- 1(b)(ii)Explain how the metre rule and set-squares show that the rod in Fig. 1.2 is horizontal.1 mark
- 1(c)(i)Describe how to check that end A is exactly over the 0 cm mark.1 mark
- 1(c)(ii)Calculate their average N_av to two significant figures.1 mark
- 1(d)(ii)On Fig. 1.6 plot l/cm on the y-axis against N_av on the x-axis, starting at (0,0), and draw a smooth best-fit curve.4 marks
- 1(d)(iii)Use two pairs from Fig. 1.5 or your Fig. 1.6 graph to show N_av is not inversely proportional to l.2 marks
- 1(d)(iv)Why does the student start with the Fig. 1.4 square card of side 19 cm and cut it smaller, rather than start at 3 cm?1 mark
- 2(a)(i)On Fig. 2.1 mark and label P at the midpoint of side AB of the triangular prism.1 mark
- 2(a)(ii)On Fig. 2.1 draw the normal to side AB at P.1 mark
- 2(a)(iii)On Fig. 2.1 draw an incident ray directed towards P at an angle of incidence of 40°.1 mark
- 2(b)Describe how to find and draw the complete path of that ray through the prism in Fig. 2.1.4 marks
- 3(a)(i)State the weight shown, with a unit.1 mark
- 3(a)(ii)Explain why the student must stand still when reading the scales in Fig. 3.1 and Fig. 3.2.1 mark
- 3(a)(iii)Why is it more accurate to read the Fig. 3.2 bathroom scales from directly above?1 mark
- 3(b)(i)Why must the force increase slowly?1 mark
- 3(b)(ii)Why is the box placed near the edge of the bench in Fig. 3.3?1 mark
