Answer:
B
Explanation:
Absolute advantage is the capability of a commercial entity to produce goods using fewer resources compared to rivals. Using the same inputs, an entity with an absolute advantage produces a larger output compared to competitors. It means the firm has a lower marginal cost of production. Therefore, its products will have the lowest prices in the market.

Answer:
1961 kJ
Explanation:
Since the mass of each substance is 1 kg, the heat required to change a substance at is boiling point is its latent heat of vapourization, L. For a given mass, m, the quantity of heat Q = mL
For liquid water, m = 1 kg and L = 2256 kJ/kg.
So, quantity of heat required is thus Q₁ = 1 kg × 2256 kJ/kg = 2256 kJ
For liquid mercury, m = 1 kg and L = 295 kJ/kg.
So, quantity of heat required is thus Q₂ = 1 kg × 295 kJ/kg = 295 kJ
The amount their thermal energies differ is thus Q₁ - Q₂ = 2256 kJ - 295 kJ = 1961 kJ
Answer:
a) -31.36 m/s
b) 50.176 m
Explanation:
<h2>a) Velocity of the bag</h2>
This is a problem of motion in one direction (specifically vertical motion), and the equation that best fulfills this approach is:
(1)
Where:
is the final velocity of the supply bag
is the initial velocity of the supply bag (we know it is zero because we are told <u>it was "dropped", this means it goes to ground in free fall</u>)
is the acceleration due gravity (the negtive sign indicates the gravity is downwards, in the direction of the center of the Earth)
is the time
Knowing this, let's solve (1):
(2)
Hence:
Note the negative sign is because the direction of the bag is downwards as well.
<h2>b) Final height of the bag</h2>
In this case we will use the following equation:
(3)
Where:
is the distance the bag has fallen
remembering <u>the bag was dropped</u>
is the acceleration due gravity (downwards)
is the time
Then:
(3)
(4)
Finally:
