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:
According to the public interest model, government tries to enact laws, regulations, and policies that benefit the public. The private interest (or public choice) model, by contrast, suggests that government officials enact laws that are in their own private interest.

Answer:
1: people not being aware by crossing the road while it is busy 2: people obstructing the road 3: a person could have gotten out of their car and still been in the road
Answer:
C. historical background
Explanation:
According to my research on natural disaster warning procedures, I can say that based on the information provided within the question all of the answers provided except for historical background will elicit a quick response from the public. In order for the public to react quickly to an upcoming dangerous event they need to know how bad the event will be, how likely it is to happen, and what they can do to protect themselves. Historical background will not provide any help to the public.
