DEFINITION of 'Aggregate Demand'. The total amount of goods and services demanded in the economy at a given overall price level and in a given time period. It is represented by the aggregate-demand curve, which describes the relationship between price levels and the quantity of output that firms are willing to provide.

Answers. Best Answer: Up to about 120 decibels, which is about as loud as a gunshot. Some of the factors that affect the loudness are energy released, the environment, and of course the distance you are from the lightning.
1 The estimated peak power per lightning stroke is 10^12 watts (1,000,000,000,000 watts or 1,000 Giga Watts). The total energy in a large thunderstorm is thought to be enough to power the whole of the USA for 20 minutes.  A tall thunderstorm cloud can hold over a 100 million volts of potential. The voltage potential in a lightning bolt is proportional to its length, and varies depending on the diameter of the bolt, air density and impurities of the air (humidity, dust, ash).
