The North Korean economy is based largely around self-sustainability. Everything is owned by the government, everything is planned by the government. How much, in which way, in what will be produced and consumed is planned by the government. This results in a very fragile economy above which always lurks the possibility of crack down. The slightest mistakes in the planning, or if some natural disaster occurs, always leads to huge economic problems. It is very common that the people are suffering from malnutrition because the planning didn't turned out as predicted. The economy has growth one year, stagnates another, drops in the next, and it is all very unpredictable.
Flappers should be the answer
Answer:
A. Use concrete reinforcers even when children are intrinsically motivated to learn.
Explanation:
Concrete reinforcement is carried out by giving either reward or discouragement to motivate the children into doing a behavior that we want them to.
When children are already intrinsically motivation to learn, this type of reinforcement is no longer necessary and doing that possess the risk to actually stray the children's motivation away from learning by themselves.
The correct answer to this open question is the following.
Although you did not attach options for this question, we can comment on the following.
The two events which ended the time of primitive society started the time of animal husbandry society were the end of humans being nomads and the beginning of the Neolithic Revolution.
When humans established between the Rivers Tigris and Euphrates, in the Middle East, they formed the first and oldest civilization on planet Earth: the Sumerians.
There, they developed new and advanced agriculture techniques and could prosper learning the times of the flooding of the rivers. That flooding left a very fertile soil to grow crops. That is why they could establish powerful city-states such as Lagash, Ur, Kish, Nippur, Uruk, or Eridu.
The Neolithic Revolution is also known as the Agriculture Revolution. That is when Sumerians started to plant seeds and domesticate animals.
Automatic-adjusting fog-steam nozzle provides a flow between 90 and 225 gpm (340 and 852 lpm).
<h3><u>
What is a nozzle?</u></h3>
- A nozzle is a tool used to change the characteristics of a fluid flow as it leaves (or enters) a closed chamber or conduit, particularly to enhance velocity.
- A nozzle is typically a pipe or tube with a variable cross sectional area that is used to control, direct, or alter the flow of a fluid (liquid or gas).
- Nozzles are widely used to control the stream that emerges from them in terms of flow rate, speed, direction, mass, form, and/or pressure. The fluid's pressure energy is lost as its velocity rises in a nozzle.
A portion of the enthalpy of steam is transformed into kinetic energy as it expands from a higher pressure to a lower pressure through the steam nozzle, which is a channel with variable cross sections.
Consequently, a nozzle is an apparatus created to raise the steam's velocity.
