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.

The correct answer is option B. The three main European rivals in North America were England, France and Spain. These three countries conducted wars against each other in North American territory so that they could all keep their colonies and expand the territory over their countries could rule. At the end of The French and Indian War, England would be the clear winner out of the three, with the most territory under its power.
