<span>The due process model and the crime control model. The crime control model follows a more conservative ideal and follows that idea that the repression of crime is the most important factor in maintaining society . Whereas the due process model is a more liberal approach and follows the values of fairness and justice.</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.

Answer:
B). A Cross-sectional research design.
Explanation:
A cross-sectional research design is demonstrated as a kind of observation study that involves the study and analysis of a representative subset from the population at a particular point of time.
In the given example, Tucker is employing 'cross-sectional research design' as he selects a representative subset('a group of 5-year-olds, a group of 10-year-olds, and a group of 15-year old) from the population at the same time for study and analysis(by interviewing them) . This implies that Tucker adopts a '<u>cross-sectional research design</u>.'
Answer: When the cars are allowed to park anywhere
Explanation: What is Entropy? This is a situation of disorderliness. An entropy can be high or low. An entropy is high when an area or a place is in chaos. while a low entropy is a state of orderliness.
The parking lot that contains 50 cars will have a higher entropy when the place in chaos or dis orderly that means when cars are parked anywhere in the park without a sense of orderliness while the entropy will be low if the cars are packed in an orderly manner.
