Simple correlation question

#1
If i have two independent (A and B) variables and one dependent (C) can i compare intensity of corellation? Both are significant, but first corellation is 0.677 (between A and C) and second (between B and C) is 0.198. Can i say that first is higher intensity, but both are significanf?

I think you can only talk about the magnitude of the correlation not "significance". Unless you run a simple linear regression and assess the assumptions perhaps.
