For example, they have a separation of powers into executive, legislative and judicial, and most states have a bi-cameral legislitive branch, similarly to the federal government.
True!
Northern city is the answer
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.
