 Die optiese mikrograaf hieronder (links) toon korrels van perliet vir 'n eutektoïede staal met 'n skematiese diagram (regs) van die deursnee van die gepoleerde en daaropvolgende geëtste oppervlak van hierdie monster. Kies die mees korrekte stelling. Vertaling:   Microscope lens = Mikroskoop lens; Polished = gepoleer; Etched = geëts; Cementite = sementiet; Ferrite = ferriet.

Accepted Answer

The etchant dissolves the ferrite more readily than the cementite. / 
 Die etsmiddel los die ferriet makliker op as die sementiet.

Answer

The etchant dissolves the cementite more readily than the ferrite. /  
 Die etsmiddel los die sementiet makliker op as die ferriet.

Answer

The etchant dissolves the cementite and ferrite at equal rates. /   
 Die etsmiddel los die sementiet en ferriet teen gelyke tempo op.

Answer

The etchant has no effect on the material. /  
 Die etsmiddel het geen effek op die materiaal nie.
