On what platform do you use
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.

When varying greatly in size as a result of flooding or evaporation, this means that it has to be a body of water. The only body of water provided (Whose location is correct) is Great Salt Lake, Utah.
Reapportionment Act of 1929 was passed in order to put in place a permanent method for dividing a constant 435 in the US house of representative in accordance with census. According to the constitutions, each state was supposed to have one representative in the house of representative. As the population of US increase, it becomes difficult how to choose members of house of representative, hence this law.
Answer: "parapraxis" ; or "Freudian slip" .
