Give an example of an element that displays strong electronegativity - explain why? An example of an element that displays weak electronegativity - explain why?

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

answer by yourhope:

how do models compare to real-world objects?

d. most models represent a real-world object in a simpler way.

if you mean hydrogen and oxygen then water is the product

l dont know l am s sorry
