A simple way to model air pollution over a city is with a box model that assumes complete mixing and limited capability for the polllution to disperse horizontally or vertically except in the directin of the prevailing winds (for example, a town locted in a valley with an inversion later above it). Consider a town having an inversion at 250m, a 20-km horizontal distance perpendicular to the wind, a windspeed of 2m/s, and a carbon monoxide emission rate of 60kg/s. Assume the CO is conservative and completed mixed in the box. Required:
What would be the CO concentration in the box?

i don't understand really? can u provide more information

u should make a machine that can make ice cream fresh!

the clapeyron equation (also called the clausius-clapeyron equation) relates the slope of a reaction line on a phase diagram to fundamental thermodynamic properties.

answer:

Power braking's benefits

Among the big advantages of a power braking system are it's: Regarded as safer. The heat caused by the friction of drum brakes causes them to wear down. Because disc brake systems have better heat distribution, they're more efficient
