The Scientific Method. The Scientific Method is an organized way that helps scientists (or anyone!) answer a question or begin to solve a problem. There are usually six parts to it. 1  Purpose/Question â What do you want to learn? 2  Research â Find out as much as you can. 3  Hypothesis â After doing your research, try to predict the answer to the problem.  Experiment â The fun 1  part! Analysis â Record what happened during the experiment.
Economic Definition of long-run average cost. Offline Version: PDF. Term long-run average cost Definition: The per unit cost of producing a good or service in the long run when all inputs are variable. In other words, long-run total cost divided by the quantity of output produced.
Long Run Average Cost Curve: In the long run, all costs of a firm are variable. The factors of production can be used in varying proportions to deal with an increased output. The firm having time-period long enough can build larger scale or type of plant to produce the anticipated output.athematically expressed, the long-run average cost curve is the envelope of the SAC curves. In this figure 13.7, the long-run average cost curve of the firm is lowest at point C. CM is the minimum cost at which optimum output OM can be, obtained.
