The republic fell because the size of the empire was to big, the events were moving rapidly and there was no time for bureaucracy, voting, debating and so on.

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:
(B) Noise, pyschological
Explanation:
Psychological noise occurs when the person trying to heed the propagated message begins to let his mind wander over another subject. It is a noise present in the head of the person, which ends up impeding the understanding of the message, that is, the communication itself. Like Tracy, who is trying to make a communication about work, but her mind insists on thinking about the death of her dog.
