1(a)[2]
(For d = 90.0 cm): T = 1.91
T2 = 3.65 (3.6481)
1(b)[1]
T and T2 values present for 45cm, AND T2 both quoted to 3 OR both quoted to 4 significant figures
1(c)[2]
t and T in s
T2 in s2
1(d)[1]
(Timing) errors (due to reaction time) less significant / (same) error is spread over a longer time.
1(e)[1]
Use of set square or similar horizontal aid OR metre rule close to bob / pendulum
1(f)[1]
Use of fiducial point / counting from when pendulum passes the vertical / start counting from zero.
1(g)[1]
100 (cm) < x < 140 (cm)
1(h)[2]
At least 3 additional values
No value greater than distance x as stated in (g)
