Answer:
The short-term memory
Explanation:
The memory is an abstract concept of the mind to store and retain information. It is a major function of the cerebral cortex in the brain. Memories are created from our daily experience, which is encoded systematically for productive purposes. For a memory to be created, the brain encodes external information or data, it is stored for a period of time and would be retrievable when needed.
The memory is categorized into long-term memory, short-term memory and working memory. The long term memory can be implicit, explicit or autobiographical long term memory.
Short term memory is controlled by the cerebral cortex, which is used to hold information currently in use, while cerebral cortex maintain attention and perpetual awareness for the active session.

Because of this, they use the Mexicans as the scapegoat and told American citizens that they're the cause of the Depression. This lead to some Americans demanded Mexican people to no longer be considered as a part of their society. </span>
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.
