Answer:
The amount of air resistance an object experiences depends on its speed, its cross-sectional area, its shape and the density of the air.
Explanation:
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 )
Answer:
B) Physical properties cannot be observed without changing the identity of the material.
Using the metric units kilometer (km) and meter (m), as seen in the picture of the ladder method example. So, the answer would be 14km = 14000m
