Suppose you pour water into a container until it reaches a depth of 12 cm. Next, you carefully pour in an 8.5 cm thickness of ol
Phantasy [73]

Answer:

the pressure at the bottom is approximately 103264 Pa

Explanation:

From Pascal's law, the pressure at the bottom of the container is the pressure from the atmosphere and the columns of water and olive , therefore

Pressure at the bottom = Pressure at the surface of the liquid ( atmospheric pressure) + pressure of the column of water + pressure of the column of olive oil

since

- Pressure at the surface of the liquid = atmospheric pressure = 101325 Pa

- pressure of the column of water = density of water * gravity * level of water

= 1000 kg/m³ * 9.8 m/s² * 0.12 m = 1176 Pa

- pressure of the column of olive oil=  density of olive oil* gravity * level of olive oil = 916 kg/m³ * 9.8 m/s² * 0.085 m = 763 Pa

therefore

Pressure at the bottom = 101325 Pa + 1176 Pa + 763 Pa = 103264 Pa

density of olive oil was taken from internet sources ( we can check that is lower than the one of water, and thus it floats )
