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.

E solar energy! Is ur answer
Answer:
competence
Explanation:
A theory by Richard Ryan and Edward Deci suggests that there are three psychological needs that need to be balanced in order for people to experience a deep sense of well-being. They are relatedness, autonomy and competence.
The theory by Edward Deci & Richard Ryan that states that people need autonomy, competence, & relatedness in order to feel intrinsic motivation is Self-determination theory. The theory suggest the these three characteristics will make an individual have deeper sense of well being and feel intrinsic motivation.
Intrinsic motivation is the idea of an individual doing what he is doing because of what he stands to gain from it. He feels joy doing anything it is because it makes him feel fulfilled.
<u>Answer:
</u>
Following Germany's unprovoked attack on Belgium in violation of Belgian neutrality, Great Britain declared war on Germany is a TRUE statement.
<u>Explanation:
</u>
- The treaty that was signed between Great Britain, Germany and a few other nations regarding the neutrality of Belgium in 1839 was breached by Germany in 1914 by invading Belgium through an unprovoked and spontaneous military action.
- The German Confederation despite being a signatory to the treaty that ensured the protection of Belgium's neutrality attacked Belgium. This action was not welcomed by Great Britain and was responded to by calling a war against Germany.
Answer:
Deductive Reasoning
Explanation:
The given condition is an example of deductive reasoning. Two arguments are related that bring a valid conclusion given the conditions hold true to both.
Deductive Reasoning: Process of making logical arguments by facts and logic.
Deduction:
Condition 1--- Jason can run 100 meter in 15 seconds
Condition 2--- Sarah is faster at racing any distance
Conclusion--- Sarah can run 100 meter in less than 15 seconds
Reason: Since Sarah is faster than Jason in any race therefore she can win run faster than him at any given condition. Jason runs 100 meter in 15 seconds which means Sarah can run the same distance in less than 15 seconds as she is faster than him.
