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.

B is not the correct answer
Answer:
C. worker productivity is governed by scientific law
Explanation:
The creator of scientific management believed that worker productivity is governed by scientific law. In Taylor's scientific management theory, he believed that there were universal laws which governed efficiency and that these laws were independent of human judgment. The goal of Scientific Management was to find this “one best way” of doing things as efficiently as possible.
<u>Answer</u>:
Cell phones contain rechargeable batteries that transform chemical energy into electrical energy. When using your cell phone, electrical energy is first transformed into <u>Electromagnetic waves </u>that are transmitted through the air.
<u>Explanation</u>:
When chemical energy is converted into electrical energy in cell phones, then this electrical energy firstly transformed or converted into electromagnetic waves which travels through air. Then this electromagnetic wave is converted into sound energy due to which users are able to listen audio, music, movies etc on their mobile phones.
The electrochemical energy that stored in a cell is removed as electrical energy in the process of discharging. There are so many other thermal and electrochemical processes taking place at the same time.
Answer:
Slaves had few legal rights: in court their testimony was inadmissible in any litigation involving whites; they could make no contract, nor could they own property; even if attacked, they could not strike a white person. There were numerous restrictions to enforce social control: slaves could not be away from their owner’s premises without permission; they could not assemble unless a white person was present; they could not own firearms; they could not be taught to read or write, nor could they transmit or possess “inflammatory” literature; they were not permitted to marry.
