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:2 change february to February
This is a common pronoun hence one has to use a capital letter for a pronoun. Those are the name for things like the names of the cities or schools , general terms for common things.
The power of the media to draw the public attention to the particular issues and the problems is called as agenda-setting.
Agenda-setting list of issues that government officials and non-governmental people who are closely associated with government officials always pay serious attention to..be the center of attention. Setting an agenda is also very important politically, as the public agenda influences the political agenda. That is, candidates try to focus on issues that the public wants to hear. Agenda-setting theory suggests that media outlets shape the political debate by determining the most important issues and presenting them on news programs. The media has been described as the primary authority in choosing which news to report and prioritize based on what they believe people will be interested in.

Answer:
Negative reinforcement
Explanation:
Negative reinforcement can be defined as the acts or behaviour carried out by person in order to encourage someone to do what he /she said.
Negative reinforcement are often use to encourage or motivate someone and as well change the person behaviour. It also strengthened a person behaviour by removing negative result.
This example "Elton's mother has been nagging that he should practice at the piano for the upcoming competition. Elton eventually complies to stop her nagging" simply illustrates NEGATIVE REINFORCEMENT because Elton's mother was nagging in order to encourage Elton's to practice the piano for the upcoming competition and as well change is behaviour in which Elton finally complies to do what she said due to her nagging.
