Q:

Why is burning coal a major source of pollution?

Answer

Coal is chemically complex fuel. Whenever it is burned, gases are given off and particles of ash, called "fly ash," are released. Release of sulfur from burning into the air. The sulfur in coal combines with oxygen to form sulfur dioxide, which can be a major source of air pollution if emitted in large enough quantities. This stuff comes back as acid rain when it attaches itself to a raindrop. 


 


Today, many of the effects of coal burning have been reduced significantly or eliminated. This is super-nasty and is only stopped by buying low-sulfur coal from Montana or Wyoming. The eastern power plants have to pay to move the coal from out west and this increases the price of power production.

Q:

In economics, if a good is inelastic,

A) its supply or demand is not sensitive to price changes. B) consumers have lost an interest in purchasing it.
C) producers have lost an interest in manufacturing it. D) its supply or demand is too sensitive to price changes.
 
Answer & Explanation Answer: A) its supply or demand is not sensitive to price changes.

Explanation:

If the percent change in quantity demanded is less than the percent change in price, economists label the demand for the good as inelastic.

A good that is inelastic does not have very stretchy demand. In economic terms, the quantity demanded does not change a lot when the price changes.

 

So, if the price of a good increases by 10 percent and the quantity demanded decreases by only 5 percent or less than 10, that good is said to have inelastic demand.

 

Hence, in this case, consumers are not considered very sensitive, or responsive, to a change in the price of that good.
