When a cognitive function relies on one cerebral hemisphere more than the other, this phenomenon is known as lateralization.
This means that each side of the brain specializes in some things and works harder on those things than the other side and some neural functions or cognitive processes are specialized to one side of the brain or the other.
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.

Answer:
There are many disadvantages of exclusion in societies. One disadvantage is that social exclusion creates parallel sub-societies and sub-cultures within a society, that threaten the social order of a particular area.
Another disadvantage, related with the first, is that exclusion leads to little dialogue among different social groups. This can greatly increased social conflict, political extremism and radicalization, and in extreme cases, as history has shown many times, could lead to civil war.
