TABULATE:
i:1,2,3,4,5,
L(cm): 80.00,70.00,60.00,50.00,40.00
t1(s): 17.87,16.22,16.09,14.08,13.28
t2(2): 17.56,16.46,15.09,14.77,13.36
t(s)mean: 17.715,16.340,15.590,14.425,13.320
T(t/10)s: 1.7715,1.6340,1.5590,1.4425,1.3320
LogT(s): 0.2483,0.2133,0.1928,0.1591,0.1212
Log L(cm): 1.9031,1.8451,1.7782,1.6990,1.6021
Log T*10^-2(s): 24.83,21.33,19.28,15.91,12.12
Log L*10^-1(cm): 19.031,18.451,17.782,16.990,16.021
SLOPE(s) = (LogT2*10^-2 – LogT1*10^-2)(/Log L2 *10^-1 – LogL1*10^-1) = (21.33-12.12(s))*10^-2/(18.50-16.02(cm)*10^-1)
=3.714*10^-1
=0.3714cm^-1

1axi)
i) I ensured supports of pendula were rigged
ii)I avoided parallax error on meter rule/stop watch
1bi) simple harmonic motion is the motion of a body whose acceleration is always direct towards a fixed point and is proportional to the displacement from the fixed points
1bii)
T=1.2secs
Log 1.2=0.079
0079 shown on graph with corresponding Log L read L correctly determined

TABULATE:
x(cm):10,20,30,40,50,60
V(v):0.65,0.75,1.00,1.20,1.45,1.55
I(A):0.20,0.30,0.35,0.40,0.45,0.55
LogV(v):-0.187,-0.125,0.000,0.079,0.161,0.190
LogI(ohm):-0.699,-0.523,-0.456,-0.396,-0.391,-0.360
SLOPE(s):=( LogI2-LOgI1)/(LogV2-LogV1)
=-0.2-(-0.7)/0.3-(-0.2)
=0.5/0.5
=1AV^-1
3axi)
i) I ensured clean/tight terminals
ii)I opened key when reading was taken
3bi)

ii)voltage/current through the bulb increases
3bii)
i)diode
