A student is required to determine the acceleration due to gravity (g) using a simple pendulum. The length of the pendulum string is measured with a metre rule and recorded as 1.00 m (to the nearest millimetre). The time for 20 complete oscillations is measured with a stop‑watch. The experiment is repeated three times and the recorded times are shown in the table below. | Trial | Time for 20 oscillations (s) | |-------|------------------------------| | 1 | 40.2 | | 2 | 40.5 | | 3 | 40.1 | Using the data, answer the following:

( a )

Calculate the average period (T) of the pendulum in seconds.

( b )

Using the period obtained in (a), calculate the value of g (in m s⁻²) to two decimal places. Use \(g = 4\pi^{2}L/T^{2}\).

( c )

State two possible sources of error in this experiment and suggest one method to reduce each error.

( d )

Comment on the reliability of the value of g obtained in part (b) compared with the standard value of 9.81 m s⁻².
