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.

fossil fuels make up the biggest percentage of air pollution
As a result of it being <u>easy </u>to miss that a meter has changed range, a lot of instructors started requiring their students to use <u>manual ranging. </u>
<h3>Why do the instructors require manual ranging?</h3>
When using automatic ranging to work with the meter of an automotive, there is no flashing light that is given if the meter changes the range it is using.
Students can therefore miss this change quite easily. Working with manual ranging however, the meter will not be able to change ranges unless the students sets it this way. It is therefore harder to miss a change in range.
