1. the activation energy to form interstitial carbon in iron at room temperature is around 0.77 ev, and in vanadium at room temperature, it is slightly less at 0.74 ev. a. why the difference? consider the physical differences between atoms of these two elements.

Which of the following changes will increase the capacitance of a parallel-plate capacitor? (there could be more than one correct choice.) a) increase the charge on the plates b) decrease the poten5al between the plates c) increase the potential between the plates d) introduce a dielectric material between the plates e) decrease the separation between the plates
