(1 Point)

a)Mini mills , power point and transistors radios

b)Mini mills for steel , high speed CMOS and transistor radios

c)Mini mills , power point and transistors

d)high speed CMOS, transistors and power point

Answer 1

C is correct optiin

An integrated steel mill has all the functions for primary steel production In a mini-mills, electricity is used to melt (primarily) scrap steel. ... Minimills make steel from scrap steel or scrap substitutes in an electric arc furnace (EAF).

Drafting softwares were disrupted by power point .

*In the 1940s, the invention of semiconductor devices made it possible to produce solid-state devices, which are smaller, more efficient, reliable, durable, safer, and more economical than thermionic tubes. Beginning in the mid-1960s, thermionic tubes were being replaced by the transistor.
