Complete the data table for an experiment involving period and length, converting cm to meters.

Step 1: Complete the data table.
The period $T$ is calculated as $\frac{\text{Mean } t}{20}$. The value $T^2$ is the square of $T$. The length $l$ must be converted from cm to meters. We will use the values for Mean $t$, $T$, and $T^2$ as provided in the image's table, assuming they are the intended values for the experiment, and convert $l$ to meters.

$l$ (cm)	$l$ (m)	Mean $t$ (s)	$T$ (s)	$T^2$ (s$^2$)
