An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
Ashima has an absolute advantage in both zucchini and watermelon production.
Loc's opportunity cost of producing 1 pound of watermelon is 3 pounds of zucchini, while Ashima's is 2 pounds of zucchini.
Ashima has a comparative advantage in watermelon production because her opportunity cost is lower.
Loc has a comparative advantage in zucchini production.
The final answer is: Ashima has an absolute advantage in the production of zucchini, and Ashima has an absolute advantage in the production of watermelon. Loc's opportunity cost of producing 1 pound of watermelon is 3 pounds of zucchini, whereas Ashima's opportunity cost of producing 1 pound of watermelon is 2 pounds of zucchini. Because Loc has a hi g h er opportunity cost of producing watermelon than Ashima, Ashima has a comparative advantage in the production of watermelon, and Loc has a comparative advantage in the production of zucchini.
Explanation
Determining Absolute Advantage First, we need to determine who has the absolute advantage in producing zucchini and watermelon. Absolute advantage means who can produce more of a good with the same amount of resources.
Absolute Advantage in Zucchini Looking at the table, Ashima can produce 8 pounds of zucchini per acre, while Loc can only produce 6 pounds of zucchini per acre. Therefore, Ashima has the absolute advantage in zucchini production.
Absolute Advantage in Watermelon Ashima can produce 4 pounds of watermelon per acre, while Loc can produce 2 pounds of watermelon per acre. Therefore, Ashima has the absolute advantage in watermelon production.
Understanding Opportunity Cost Next, we need to calculate the opportunity costs. Opportunity cost is what you give up to produce something else.
Loc's Opportunity Cost Loc's opportunity cost of producing 1 pound of watermelon is the amount of zucchini he has to give up. He can produce 6 pounds of zucchini or 2 pounds of watermelon on an acre. So, for every 2 pounds of watermelon, he gives up 6 pounds of zucchini. Therefore, for 1 pound of watermelon, he gives up 6/2 = 3 pounds of zucchini.
Ashima's Opportunity Cost Ashima's opportunity cost of producing 1 pound of watermelon is the amount of zucchini she has to give up. She can produce 8 pounds of zucchini or 4 pounds of watermelon on an acre. So, for every 4 pounds of watermelon, she gives up 8 pounds of zucchini. Therefore, for 1 pound of watermelon, she gives up 8/4 = 2 pounds of zucchini.
Understanding Comparative Advantage Now, we determine comparative advantage. Comparative advantage means producing a good at a lower opportunity cost.
Comparative Advantage in Watermelon Loc's opportunity cost of producing 1 pound of watermelon is 3 pounds of zucchini, while Ashima's opportunity cost of producing 1 pound of watermelon is 2 pounds of zucchini. Since Ashima has a lower opportunity cost, she has the comparative advantage in watermelon production.
Comparative Advantage in Zucchini Since Ashima has the comparative advantage in watermelon production, Loc must have the comparative advantage in zucchini production.
Final Answer Therefore, Ashima has an absolute advantage in the production of zucchini, and Ashima has an absolute advantage in the production of watermelon. Loc's opportunity cost of producing 1 pound of watermelon is 3 pounds of zucchini, whereas Ashima's opportunity cost of producing 1 pound of watermelon is 2 pounds of zucchini. Because Loc has a higher opportunity cost of producing watermelon than Ashima, Ashima has a comparative advantage in the production of watermelon, and Loc has a comparative advantage in the production of zucchini.
Examples
Understanding absolute and comparative advantage is crucial in international trade. For example, if the US can produce both cars and wheat more efficiently than China (absolute advantage), it doesn't mean the US should produce everything. If China can produce wheat at a lower opportunity cost (comparative advantage), it benefits both countries for China to specialize in wheat and the US in cars, leading to more efficient global production and trade. This principle applies to individual farmers deciding what crops to grow, just like Loc and Ashima.
The number of electrons that flow through an electric device delivering a current of 15.0 A for 30 seconds is approximately 2.81 × 1 0 21 electrons. This is calculated by first finding the total charge using the formula Q = I × t and then dividing by the charge of an electron. The charge of a single electron is 1.6 × 1 0 − 19 C .
