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:
Option C
Explanation:
It was during the time of medival Europe (11th & 12th century), when popes challenged the European monarchies over the freedom to choose bishop. This conflict was then resolved by the "Concordat of Worms" through a compromise agreement between the two parties. This conflict led to winning of great dukes and abbots and falling of the German empire
Hence, option C is correct
Answer:
Better education for public officials
Answer:
Learning
Explanation:
Learning is like reflexes and instincts allows organism to adapt to its environment. learned behaviour involve change and experienced. learning is a relatively permanent change in behaviour.
