Exposure to the very high intensity electromagnetic fields found in the immediate vicinity of certain sources such as radar installations and TV or radio transmitters can produce electrical shock or a variety of heating effects, which may range from a sensation of warmth to burns and eventual cataract formation.
S 1 is a vertical, perfectly inelastic, supply curve. This represents 'momentary' supply. In most industries, if a firm was asked to produce a large order immediately, it simply would not be able to do it, regardless of the price offered for the order. Supply is perfectly inelastic in the very short run.
Explain shifts in aggregate supply and their impact on the economy. The aggregate supply curve shows how much output is supplied by firms at different price levels. The short-run aggregate supply curve is affected by production costs including taxes, subsides, price of labor (wages), and the price of raw materials.
