1)
Tabulate
s/n= 1,2,3,4,5
L(cm)= 130,110,90,70,50
T1(sec)= 45.70,42.00,38.00,33.10,28.70
T= 2.29,2.10,1.90,1.66,1,44
T^2= 5.22,4.41,3.61,2.74,2.06
L=100,80,60,40,20

1)
-precautions-
Take Any Two
i)I avoided conical oscillation 
ii)I avoided drought
iii)I avoided parallax error in taking reading from the metre rule
iv)I avoided zero error in taking reading from the stop watch

(1aix)
Slope(s) = Δvertical/Δhorizontal
=1.90 – 1.55/9.49 – 7.75
= 0.35/1.74
S = 0.201
(1ax)
g = 4π²/S²
= 4 ×(3.142)²/(0.201)²
= 977.4cm/s²

(1axi)
(i) I ensured the angle of oscillation is relatively
small.
(ii) I ensured that no external force is added to
the system of oscillation.
(iii) I ensured the oscillation is perfect

3)
Tabulate

3)
-precautions-
take any two

ii)I ensured tight connections at the terminals
iii)I avoided parallax error when taking reading from the ammeter.
