(1 point) Dumping and other material-handling operations near a landfill may result in contaminated particles being emitted into the surrounding air. To estimate such particulate emission, the following empirical formula can be used: E(V,M)=k(0.0032)(V5)1.4(M2)−1.3E(V,M)=k(0.0032)(V5)1.4(M2)−1.3 where EE is the emission factor (in pounds of particles released into the air per ton of soil moved), VV is the mean speed of the wind (mph), MM is the moisture content of the material (given as a percentage), and kk is a constant that...
