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.
Water, when found in nature springs and aquifers, is naturally alkaline often due to the presence of alkaline minerals like calcium, magnesium, potassium and sodium. Alkaline is defined as having a pH value greater than 7.0. pH stands for potential for hydrogen, pH is a measure of the acidity or alkalinity of a solution. The pH scale runs from 0 to 14, with 7.0 considered neutral. pH values below 7.0 are considered acidic, and pH values above 7.0 are considered alkaline.
