Shortage<span> is a situation in which quantity demanded is greater than quantity supplied.</span>
When quantity supplied is equal to quantity demanded, it is called equilibrium of demand. Both supply and demand are equal.
<span>When quantity supplied is greater than quantity demanded, it is called surplus. Excess supply of goods are called surplus.</span>
Answer:
little industrial development
Explanation:
just took it
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: deception;debriefed
Explanation:
Deception during the research occurs when the participants are not given the fully information about the research that they are participating on or they are given the incorrect information about what the research is about .
This is usually done in order to receive bias free answers because when people know what the research is about they may sometimes answer in a way that will give a particular response that they feel is expected theirfore not being completely true.
A debriefing is now done to establish how people felt about the actual research or research question after they have already participated in a research in order to receive a feedback report . This is where everything in now explained to them properly and accurately.
Answer:
Public smoking bans appear to significantly reduce the risk of heart attacks, particularly among younger individuals and nonsmokers, according to a new study. Researchers find that smoking bans can reduce the number of heart attacks by as much as 26 percent per year.
