Answer:
The price elasticity of a product shows how many percent the requested quantity changes as the price increases by one percent. In the normal case, the elasticity is a negative number, as demand decreases as the price increases; the reverse is extremely unusual.
In the case of large companies, however, the price elasticity of demand is usually much larger. This is so because not only characteristics such as the quality of the product are weighted, but also the brand itself has a value in itself, which sustains the variations in price. Thus, trendy brands such as Starbucks have an established clientele that will not vary due to small price variations. On the other hand, these companies offer a high variety of products, which liquefy said possibility of falling demand, granting greater elasticity.
Answer:
26: Free-Riding
27: Revolving Door
28: Interest groups can work against the "tyranny of the majority"
Explanation:
26: By definition, the free rider problem is market benefits received in a communal nature without paying for them.
27: Revolving door is when people move between roles as regulators and legislators to being a member of the industries affected
28: To me, "B" seems to be the only answer I couldn't spin in a bad light
A: could be posed as Congress being controlled by interest groups
C: obviously controlling elections through donations is a negative
D: gridlock results in a standstill where things can't get done, especially if neither group is willing to concede
The reaction between ethanol C2H5OH and water H2O is a chemical reaction and is exothermic.
Option A is correct.
<h3>What is a chemical reaction?</h3>
A chemical reaction is a rearrangement between the ions and molecules of a substance. For a chemical reaction to take place, bonds are broken in the reactants and new bonds are formed in the products.
The chemical reaction between ethanol and water is;
- This reaction is exothermic because molecules move from a higher state of energy to lower states.
- The resulting volume is also lesser than the initial volumes of the reactants according to Henry's Law, showing that heat is given off to the walls of the container.
Therefore, we can conclude that A chemical reaction occurs, as evidenced by the volume of the resultant mixture being less than the total volume of the initial components.

Power efficiency is defined as the ratio of the output power divided by the input power:
Efficiency= out/in • 100%
So, (120 - 45)J / 120J • 100% = 62.5%
