A 400 g mass m is attached between two springs, displaced a small distance downwards,
and then released so that it oscillates. The time t taken for 10 complete oscillations of the
mass is recorded. The experiment is repeated using values for m of 300 g and 200 g. The
readings are shown in the table below.

Calculate the period T of the oscillations. T is the time for one complete oscillation.
Enter the values in the table. [2]
