<span>Money is used as medium of exchange in the form of goods or item. When the farmer man traded the five cows so, that five cow will be durable to him. The cow can become his source of his income by the work done by the cattels. so the cows durability is more. Once the cow life sheds then he can make profit of it also. So, durabilty makes a major role in the characteristic of money.</span>
The thickness up to which the velocity approaches 99% of the free stream velocity. The distance measured perpendicular to the boundary by which the free stream is displaced on account of the formation of the boundary layer.
<h3>What is displacement thickness in boundary layer theory?</h3>
The displacement thickness for the boundary layer is defined as the distance the surface would have to move in the y-direction to reduce the flow passing by a volume equivalent to the real effect of the boundary layer.
The thickness of the boundary layer represented by δ is arbitrarily defined as that distance from the boundary surface in which the velocity reaches 99% of the velocity of the mainstream.

Answer: The principle of continuity
Explanation: The Gestalt Continuity Law refers to how the human brain perceives the line-elements that are grouped. Continuity theory refers in fact to the tendency of the brain to see the constituent elements as a whole, that is, the elements belong to a whole, a continuous representation of something. In this case, the brain of little Sinead perceived that all the elements that are part of the exhibit snake make up the whole, and with the perception of the brain, they continue into the living snake.
The essence of this theory is that, for example, the line is perceived as a continuation of some imagined, established direction.
