Dr. Smith conducts experiments to learn more about how individuals gather, store, and process information. Dr. Smith's theoretical perspective is best described as cognitive.
<span>Cognitive Approach is the p</span>sychological perspective concerned with how we receive, store, and process information; think/reason, and use language.
<span>When reference is made to the "poverty line", it means the specific amount of income needed for a basic standard of living.

The poverty line refers to the base level of pay considered sufficient in a specific country. Practically speaking, similar to the meaning of poverty, the official or normal comprehension of the neediness line is fundamentally higher in created nations than in creating nations.
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.
