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:
I think the word <u>ethic</u> is the answer.
‘Do this’ is definitely an assertive phrase.
The answer is neurotic trend of "moving toward people".
There are three principle neurotic trends as depicted by Karen Homey, which develop from a people system of engaging nervousness.The trends are:
Moving Toward People
Moving Against People
Moving Away From People
Answer: heredity; environment
Explanation:
There is a much better appreciation now for the influence that
environment (things like nutrition, schooling, enriched stimulation, etc),can have on intelligence - intelligence can change!
(reaction range is the name of the outer limits set by heredity)
