| Units of quantity consumed | Total utility | Marginal utility |
| 0 | - | - |
| 1 | 10 | 10 |
| 2 | 15 | 5 |
| 3 | 17 | 2 |
| 4 | 18 | 1 |
| 5 | 18 | 0 |
The table above illustrates the law of?
Diminishing returns
Diminishing marginal productivity
Diminishing marginal utility
Variable proportion
Correct answer is C
The law of diminishing marginal utility explains that all things being the same, as consumption increases, the marginal utility derived from each additional unit of a commodity declines.
What this means is that, as you consume a particular commodity, the satisfaction derived from it increases, but it gets to a point where additional consumption of that particular product will no longer give you as much satisfaction as the first few ones you consumed.
From the table above, the consumer started from 1 unit to five units, and at first, the total utility derived from consuming the product was rising from 10 -> 15 -> 17 -> 18 and remained at 18
However, the marginal utility kept declining after consuming the first unit. It moved from 10 -> 5 -> 2 -> 1 -> 0
The table below shows the short-run cost of a firm. Use it to answer the question below
| Quantity (kg) | Fixed cost ($) | Variable cost ($) | Total cost ($) | Marginal cost ($) | Average cost ($) |
| 1 | 750 | 200 | 950 | - | 950 |
| 2 | 750 | 560 | 1310 | 360 | 655 |
| 3 | 750 | 900 | P | Q | 550 |
Calculate the value of Q
$350
$340
$360
$370
Correct answer is B
To get Q, we first have to solve for P, hence we have;
Total cost (P) = fixed cost + variable
750 + 900 = 1650
Marginal cost (Q) = 1650 - 1310 = 340
| Quantity (kg) | Fixed cost ($) | Variable cost ($) | Total cost ($) | Marginal cost ($) | Average cost ($) |
| 1 | 750 | 200 | 950 | - | 950 |
| 2 | 750 | 560 | 1310 | 360 | 655 |
| 3 | 750 | 900 | 1650 | 340 | 550 |
most energetic molecules leave the surface and escape into the air.
least energetic molecules leave the surface and escape into air.
most energetic molecules leave the surface and return.
least energetic molecules leave the surface and return.
Correct answer is A
The statement that explains the observation is:
The most energetic molecules leave the surface and escape into the air.
This phenomenon is known as evaporation. In a liquid, molecules have varying energies, and the molecules with higher kinetic energies (the most energetic ones) are more likely to overcome the attractive forces within the liquid and transition into the gaseous phase. These molecules escape from the surface of the liquid into the air, gradually reducing the amount of liquid in the open dish. Evaporation is a process that occurs continuously as long as there is a liquid exposed to the air.
