Cottrell-Wolken sind Ansammlungen von Versetzungen in einem Kristallgitter, die durch die Anziehung von interstitiellen Atomen oder Legierungselementen verursacht werden. Diese Atome oder Elemente lagern sich an die Versetzungen an und stabilisieren sie. Dies führt zu einer Erhöhung der Streckgrenze des Materials, da die Bewegung der Versetzungen behindert wird. Dadurch wird das Material härter und weniger verformbar.

Texarkana Electric Company burns coal to heat the water that drives its electricity-producing turbines. The table below shows the marginal benefit of annual electricity consumption and the private marginal cost of annual electricity production.

In part c, round your answer to one decimal place. a. What is "private quantity" of electricity Texarkana Electric Company will produce each year? million megawatts per year Now assume the production of electricity also produces sulfur dioxide (a precursor to acid rain). The external cost of the sulfur dioxide increases by 20 for each 0.5 million megawatts produced. b. Fill in the external marginal cost (MC external) and the social marginal cost (MC social) columns in the table above. c. What is the socially optimal amount of electricity for Texarkana to produce if all costs and benefits are considered? million megawatts per year
