The answer to this question is C)were the first American
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: by putting restrictions that limit behaviours that may interfer with other people right or with even your own right
Explanation:
Restrictions or restrictive rules are put forward to monitor each right and make it fall in line with what is acceptable standard of behaviour for example every person has a right to drive at a particular age but still they have to follow road rules in order to be safe and limit their speed or any unacceptable behaviour on the road but also to ensure that others around them are safe.
