Answer:
Country North has the comparative advantage in the production of tractor
Step-by-step explanation:
The principle of comparative advantage states that a country should specialize in the production of goods in which it have comparative cost advantage over other nations. i.e A country should focus on the production of the goods in which it has a lower opportunity cost in producing than someone else.
The question given shows that Country North has a lower opportunity cost (which is 21 watches) if it produces 3 tractors compared to country south which has an opportunity cost of 100 watches when it produces 5 tractors.
Hence, we can say that country North has a comparative advantage in the production of Tractors over country south because its opportunity cost when its produces tractors is lower than that of the country south
Answer:
326.87
Step-by-step explanation:
Answer:
Tye answer is 5 becuase 5*31=195 and 200-5=195
The surface area of the sphere is:
A = 4 * pi * r ^ 2
Deriving we have:
A '= 8 * pi * r * r'
We clear the speed:
r '= A' / (8 * pi * r)
Substituting values:
r '= 24 / (8 * pi * 3)
r '= 1 / pi inch / sec
Then, the volume of the sphere is:
V = (4/3) * (pi) * (r ^ 3)
Deriving we have:
V '= (3) * (4/3) * (pi) * (r ^ 2) * (r')
Substituting values:
V '= (3) * (4/3) * (pi) * (3 ^ 2) * (1 / pi)
Rewriting:
V '= (4) * (9)
V '= 36 inch3 / sec
Answer:
the volume of the ice is changing at 36 inch3 / sec at that moment
