i. You have been provided with a retort stand, clamp and boss. a set of masses, a spiral spring, stop watch, split cork and other necessary  apparatus. use the  diagram above as a guide, carry out the following instructions

ii. Suspend the spiral spring vertically as shown in the diagram

iii. suspend a mass hanger on the free end of the spiral spring and add a mass m=50.0g to the hanger. pull the hanger gently downwards and release to set it into vertical oscillations.

iv. Determine the time t for 20 complete oscillations

v. evaluate the period T, of the oscillation. Also evaluate T^2

vi. Repeat the procedure for four other values of m= 70, 90, 110 and 130g. in Each case, determine t and evaluate T and T^2. Tabulate your readings

vii. Plot a graph of T^ on the vertical axis against m on the horizontal axis.

viii. Determine the slope, s, of the graph and the intercept, l, on the vertical axis.

3a)
TABULATE READINGS
R ( N ) – | 2 .00 | | 4 .00 | | 6 .00 | | 8 .00 | | 10 .00 |
1 (A ) – | 2 .85 | | 2 .21 | | 2 .00 | | 1 .75 | | 1 .65 |
R ^ – 1 – | 1 .05 | | 0 .25 | | 0 .17 | | 0 .13 | | 0 .10 |

3bi )PRECAUTIONS
i)i ensured clean terminals
ii)i avioved zero error on the ammeter used
iii)i ensured tight connection of all wires
3bii)
ohm’s law states that the current flowing through a metallic conductor is proportional to its portential difference provided that physical condition is constant i.e V x I
3c)
slope(s) = DR^-1/DI = 0.25-0.10/2.21-1.65
=0.15/0.56
slope(s)=0.27
intercept c = -0.35
evaluation
1/5=1/0.27=3.70
evalution
1/C = 1/-0.35
=-2.86
