    A correct example of growth of resources is

     

    Solution

     

     

    Economic  growth  is an increase in what an economy can produce if it is using all its scarce resources. An increase in an economy 's productive potential can be shown by an outward shift in the economy 's production possibility frontier.

     

     

  • Question 4
    1 / -0.25

     

    If many people die due to an earthquake, it will shift the country ’s PPC to the

     

    Solution

     

     

    Severe earthquake in a country leads to decline in both human as well as capital resources. As a result of which less resources are left for producing the goods. Thus decline in resources will lead to a leftward shift in the PPC.

     

     

  • Question 5
    1 / -0.25

     

    If many people die due to a flood, it will shift the country ’s PPC to the

    If there is a recession, it will shift the country ’s PPC to the

     

    Solution

     

     

    During a recession (where all resources are not being utilized), then a movement out to the production possibility curve has no real opportunity cost.

     

     

  • Question 7
    1 / -0.25

     

    Massive unemployment shifts the PPC to the

     

    Solution

     

     

    The point on the PPC where the economy was producing earlier will shift below the PPC. This is because unemployment implies inefficient use of resources and this inefficient use of resources depicted by shifting the point below PPC.

     

     

  • Question 8
    1 / -0.25

     

    For a farmer increasing sacrifice of potatoes for each unit of onions will produce _______ shape of his PPC.

     

    Solution

     

     

    Marginal opportunity cost is defined as the amount of one good that needs to be given up in order to increase the production of the other good by one unit. It is calculated as Units of good one sacrificed/ units of the other good obtained. PPC  is  concave  to origin because marginal opportunity cost increase due to law of diminishing returns.

     

     

  • Question 9
    1 / -0.25

     

    What is the SI unit of impulse?

     

    Solution

     

     

    The SI unit of impulse is Newton second. It is given by the linear momentum due to the vector change. This produces an impulse in the same direction with respect to a given time.

     

     

  • Question 10
    1 / -0.25

     

    A tutor earns Rs. 1000 per hour teaching economics. If he joins a school, he would earn on an average Rs. 300 per hour. What is the opportunity cost of teaching in school?
