Answer: Physiological needs
Explanation: Given that these are children who did not have breakfast before arriving at school and who have difficulty focusing on what Tanya is teaching until after lunch, this is about physiological needs. When students are finally able to eat and become capable of normal student activities, which is normal follow-up, it means that they have met the basic physiological needs required for normal functioning. These are not any self-actualisation or, for example, safety needs, all these other needs come only after the physiological needs have been met, and those needs include also sleep, for example.
Answer:
Mainly to invest in to attract qualified resource human from differentes countries.
Explanation:For human resource
The object must move with the speed of 
times to approximately seeing that it is contracted to exactly half of its actual length.
<h3>How is this calculated?</h3>
The length contraction experimented by the object as it approaches lightspeed, in meters per second, is described by Lorentz contraction formula:
Here, v is the current speed m/s
c is the speed of light in m/s
L' is the length of the object at rest in m
L is the length of the object at the current speed in m
Now we know that
and 
then,
Hence, r = 
Therefore, the answer is the object must travel at a speed of times the lightspeed to be contracted to one-half its proper length.
