Answer:
19600 N/m²
Step-by-step explanation:
To calculate the pressure at the bottom of a column of water, you can use the formula:
Pressure = Density × Gravity × Height
Where:
Density of water (ρ) = 1000 kg/m³ (approximate value)
Gravity (g) = 9.8 m/s²
Height (h) = 2 m
Plug in the values and calculate:
Pressure = 1000 kg/m³ × 9.8 m/s² × 2 m
Pressure = 19600 N/m²
The unit of pressure is Pascal (Pa), which is equivalent to N/m². So, the pressure at the bottom of the groundwater column is 19600 Pascal or 19600 N/m².
