To find the speed of the object, you can use the formula for speed:
\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]
In this case, the distance is 10 centimeters and the time is 2 seconds.
\[ \text{Speed} = \frac{10 , \text{cm}}{2 , \text{s}} = 5 , \text{cm/sec} \]
None of the provided options (12 cm/sec, 20 cm/sec, 2 cm/sec, 8 cm/sec) are correct based on this calculation. The speed is 5 cm/sec.
