A remotely operated camera is lowered into a flooded cave. A pressure gauge records the pressure due to the water at different depths.
| depth below the water surface in m | pressure due to the water in Pa |
|---|---|
| 0.30 | 3000 |
| 0.70 | 7000 |
| 1.10 | 11 000 |
Describe the relationship between depth and pressure due to the water. Use the data to predict the pressure due to the water at a depth of 1.60 m.
