Answer:
Here's the answer
Explanation:
To calculate the pressure at the bottom of the beaker, we need to consider the pressure due to the height of the water column as well as the atmospheric pressure.
Given:
Density of water, ρ = 1 g/cm³ = 1000 kg/m³
Height of water column, h = 12.5 cm = 0.125 m
Acceleration due to gravity, g = 10 N/kg
The pressure at the bottom of the beaker is the sum of the pressure due to the water column and the atmospheric pressure.
Pressure due to water column:
P_water = ρ * g * h
P_water = 1000 kg/m³ * 10 N/kg * 0.125 m
P_water = 1250 N/m²
Pressure at the bottom of the beaker:
P_total = P_atm + P_water
P_total = 101325 N/m² (standard atmospheric pressure at sea level) + 1250 N/m²
P_total = 102575 N/m²
Therefore, the pressure at the bottom of the beaker when it is filled to a height of 12.5 cm is 102575 N/m².
