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.

To be a good citizen, you keep up on current events, you vote, and you have a political opinions. A civic duty might be obeying the law or calling 911 in case of emergency. A civic responsibility is showing up to vote and reading the news. It is important for a community to have good citizenship because then people are more involved in government, therefore allowing for the government to work for the common good.

Answer:
Social Progressives believe the redistribution of wealth will help the lower class achieve a higher standard of living.
Explanation:
Social progressivism is based on the idea that human development are as a result of science and technology, economy and the social reforms. They are of the belief that economic inequality between the lower class and higher class and the conflicts between workers and capitalist makes a society not to progress. These social movement is of the belief that the people can make a change instead of always waiting for the government.
Social Progressives believe the redistribution of wealth will help the lower class achieve a higher standard of living.
