An experiment is carried out to measure the extension of an elastic cord for different loads.
The results are shown in the table below:
| Load / N\text{N}N | 0 | 2 | 4 | 6 |
|---|---|---|---|---|
| Length / cm\text{cm}cm | 24.3 | 25.8 | 29.5 | |
| Extension / cm\text{cm}cm | 0 | 1.5 | 3.2 | 5.2 |
Which length is missing from the table?
27.1 cm27.1\text{ cm}27.1 cm
27.3 cm27.3\text{ cm}27.3 cm
27.5 cm27.5\text{ cm}27.5 cm
27.8 cm27.8\text{ cm}27.8 cm
