Answer & Explanation Answer: D) along a production possibilities curve, increases in the production of one good require larger and larger sacrifices of the other good

Explanation:

Opportunity cost is the cost of other alternative choices for making your interested choice of work. Oppurtunity cost is also called as alternative cost.

For example on a holiday, you have two choices to do, either you can go to movie or a function. And if you chose to go to moavie, the oppurtunity cost of going to movie is the value that would have gotten if you had gone to function.

 

The law of increasing opportunity costs states that as you increase production of one good, the opportunity cost to produce an additional good will increase.

Q:

For an ideal gas, which one of the following statements does not hold true?

A) The speed of all gas molecules is same B) The kinetic energies of all gas molecules are not same
C) The potential energy of the gas molecules is zero D) There is no interactive force between the molecules.
 
Answer & Explanation Answer: A) The speed of all gas molecules is same

Explanation:

In an ideal gas, at any particular time, different particles in the gas have different speeds and hence different kinetic energies. This assumption is reasonable because as the particles collide, we expect their speed to change. Even if initial speed of all the particles was same, the molecular collisions will disrupt this uniformity.Hence statement 1 is incorrect and 2 is correct.
