__Dry and Liquid Measurements__
Explanation:
Density is defined as a material per unit volume of the material.
The determination of the density of a liquid with an aerometer is based on the principle of Archimedes' law: "Any object that is immersed in a liquid will experience a lift which is equal to the weight of the liquid being moved".
The aerometer is in the form of a hollow cylinder, so that the aerometer can be immersed in the right position (the scale is immersed in liquid), then the aerometer is filled with Pb grains. The scale on the aerometer shows the density of the liquid, the smaller the density of the liquid, the deeper the aerometer will be. Therefore the aerometer scale shows an increasing number from top to bottom.
Discrete becuase it isn't in the form Y=MX+B
They stressed the direction of all human activity toward the goal of increasing the power of the ruler and the state.
According to Sigmund Freud who is a Psychoanalyst, the deepest level of a person's consciousness will be outside the awareness of the person. According to him, the mind is divided into three levels which are called the id, ego, and superego where id is the deepest level of consciousness.
