SUMMARY
The net force on a submarine hatch at a depth of 8.5 meters in seawater with a density of 1030 kg/m³ is calculated using the formula F = PA, where P represents the pressure and A is the area of the hatch. The pressure at this depth is determined by the hydrostatic pressure plus the atmospheric pressure, resulting in a total pressure of approximately 84,000 Pa. The hatch, which has a diameter of 1.5 meters, requires a net force calculation that accounts for both the external water pressure and the internal atmospheric pressure of 1.00 atm.
