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:
Reasonable doubt standard.
Explanation:
The single most important criterion for determining the level of proof necessary for conviction in criminal trials is Reasonable doubt standard.
Reasonable doubt is the highest standard of proof need to court. It must be exceeded to to prove a convict in a criminal case. It is exclusively used in criminal cases only as the stakes are very high.

A generally accepted fact does not have to be cited in an academic paper, whereas a paraphrase, another person's opinion, and a diagram have to be cited.
