It’s the summation of weights on top of the water surface. In this case, it is the weight of the atmosphere and water above 1m. [Formula: P (depth) = Patm + (density of water*gravitational constant * depth)].

What is the pressure in Pascals at a depth of 1m below the water surfa...
Explanation:
Pressure in Fluid:
The pressure in a fluid increases with depth due to the weight of the fluid above. It can be calculated using the equation:
Pressure = Density x Gravity x Depth
where:
- Pressure is the pressure in Pascals (Pa)
- Density is the density of the fluid in kilograms per cubic meter (kg/m^3)
- Gravity is the acceleration due to gravity, approximately 9.81 m/s^2
- Depth is the depth below the surface of the fluid in meters (m)
In this case, the fluid is water, so the density of water is used.
Density of Water:
The density of water is approximately 1000 kg/m^3.
Depth:
The depth given is 1 m below the water surface.
Calculating Pressure:
Using the equation for pressure in a fluid, we can calculate the pressure at a depth of 1 m below the water surface:
Pressure = Density x Gravity x Depth
= 1000 kg/m^3 x 9.81 m/s^2 x 1 m
= 9810 Pa
Therefore, the pressure at a depth of 1 m below the water surface is 9810 Pa, which corresponds to option 'B'.
Pressure in Fluid:
The pressure in a fluid increases with depth due to the weight of the fluid above. It can be calculated using the equation:
Pressure = Density x Gravity x Depth
where:
- Pressure is the pressure in Pascals (Pa)
- Density is the density of the fluid in kilograms per cubic meter (kg/m^3)
- Gravity is the acceleration due to gravity, approximately 9.81 m/s^2
- Depth is the depth below the surface of the fluid in meters (m)
In this case, the fluid is water, so the density of water is used.
Density of Water:
The density of water is approximately 1000 kg/m^3.
Depth:
The depth given is 1 m below the water surface.
Calculating Pressure:
Using the equation for pressure in a fluid, we can calculate the pressure at a depth of 1 m below the water surface:
Pressure = Density x Gravity x Depth
= 1000 kg/m^3 x 9.81 m/s^2 x 1 m
= 9810 Pa
Therefore, the pressure at a depth of 1 m below the water surface is 9810 Pa, which corresponds to option 'B'.
