hello can somome please gelp understand the following questions. Thank you. In production theory, the long run differs from the short run in that in the long run, all of the firm's costs are fixed. the firm produces no output. all of the firm's inputs are variable. the firm's managers become inefficient.Which of the following is incorrect in the short run? Average Total Cost =( Total Fixed Cost/Quantity). Average Total Cost =( Average Variable Cost + Average Fixed Cost). Marginal Cost =( Total Variable Cost / Quantity )=( Total Cost / Quantity ). Average Variable Cost =( Total Variable Cost/Quantity).Figure 1 below shows the American Total Physical Product of Labor for the production of chairs in 2009. Figure 1 What was the American Marginal Physical Product of Labor in chairs for the second worker in 2009 ? 0 chairs. 5 chairs. 10 chairs. 15 chairs.A farmer has 50 acres of land and 20 pounds of cotton seeds. (Land and cotton seeds are considered physical capital.) He nas hired 5 workers and is now producing 150 bushels of cotton in the short run. If the arm exhibits increasing returns to scale, if the farmer doubles the amounts of land, cotton seeds, and workers he uses to oroduce, then the amount of cotton the farmer produces will double. the amount of cotton that the farmer produces will increase by more than 150 bushels. the farm's Long-run Average Total Cost (LRATC) will increase. the amount of cotton that the farmer produces will increase by less than 150 bushels..
