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: Racial groups
Explanation:
A race is based on an idea that people are divided into distinct groups based on their shared inherited physical features and shared social qualities. It is also based on visual characteristics such as skin color , cranial and facial features or even type of hair
