Drinking water in Flint, Michigan during August 2015 had concentrations of 1.9 timesthe action level for lead, which is 15 ppb recommended by the USEPA. By July 2016,lead levels were measured below the EPA action level. From 2001 to 2003 there was asimilar water crisis in Washington DC, where lead concentrations were reported over80 ppb. Washington DC residents were exposed to lead contaminated water morethan 3.5 year

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
