In the short run, the shape of the average total cost curve (ATC) is U-shaped. The, short run average cost curve falls in the beginning, reaches a minimum and then begins to rise.The reasons for the average cost to fall in the beginning of production are that the fixed factors of a firm remain the same.The change only takes place in the variable factors such as raw material, labor, etc.he, short run average cost curve falls in the beginning, reaches a minimum and then begins to rise.

The definition of alkaline is any substance having a base pH higher than 7. Certain types of food (such as broccoli) are examples of something alkaline because their pH is higher than 7. 1  of, like, or having the properties of an alkali.  having a pH more than 7.
First, we have to learn about what alkaline means. Alkalinity and acidity are measured on the pH scale, which is a scale from 0-14 that measures the concentration of hydrogen ions in compounds from batteries to food. Neutral is measured at 7.0, while acids are below 7.0 and alkaline compounds (or bases) are greater than 7.0.
