Oil and water don’t mix, and the mass density of oil is smaller than that of water. suppose water is poured into a u-shaped tube that is open at both ends until the water surface is halfway up each leg of the tube, and then some oil is poured on top of the water in the right leg. once the system comes to equilibrium, are the top of the oil column in the right leg and the top of the water column in the left leg at the same height? if not, which is higher?
the right leg (oil on top) is higher
the left leg (no oil) is higher
the two legs are the same height

The right leg (oil on top) is higher

Explanation:

Given:

The mass density of oil is lesser than the mass density of water.

This is justified by the equation:

where:

density of the liquid

acceleration due to gravity

height of the liquid column

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers
