- 2(a)(i)Calculate their average t_av to one decimal place.2 marks
- 2(a)(ii)Using your average time for ten complete swings from 2(a)(i), calculate the period T for one swing in seconds.1 mark
- 2(a)(iii)Explain why timing ten swings instead of one gives a more accurate period.2 marks
- 2(b)(ii)On Fig. 2.3 plot T/s on the y-axis against N on the x-axis, starting at (0,0), and draw a smooth best-fit curve.4 marks
