• The distance between the nail and C is x, as shown in Fig. 1.1.
Measure and record x.
x = .................................................... cm [1]
(b) • Push the bottom of the strip horizontally through a distance of approximately 5 cm.
Release the strip so that it oscillates.
• Determine the period T of these oscillations.
T = ....................................................... s [2]
