Final answer:
The total pressure at a depth of 25.0m in the sea is the sum of the atmospheric pressure (1.05 × 10^5 Pa) and the water pressure (2.55 × 10^5 Pa), which equals 3.60 × 10^5 Pa.
Step-by-step explanation:
The total pressure experienced by a diver at a depth in the sea is the sum of atmospheric pressure and the pressure due to the water column at that depth. To calculate the total pressure at a depth of 25.0m, you simply add the atmospheric pressure and the water pressure together. In this case, the atmospheric pressure is 1.05 × 105 Pa and the pressure due to the sea water is 2.55 × 105 Pa.
The total pressure at this depth can be calculated as follows:
Total pressure = Atmospheric pressure + Pressure due to sea water
Total pressure = (1.05 × 105 Pa) + (2.55 × 105 Pa)
Total pressure = 3.60 × 105 Pa
Therefore, the total pressure at a depth of 25.0m in the sea is 3.60 × 105 Pa.
