Explanation:
Filling in blanks is a series of reading the context around the blank and maybe a little research to double check. I picked these answers because they sounded right and fit the context and also did some research to double check some blanks (eg. Neutron). Sometimes, it’s even trial and error. Nevertheless, keep trying!
Yes berkelium is highly flammable
Your answer would be D, single replacement
Answer:
The equivalent circuit for the electrode while the electrolyte gel is fresh
From the uploaded diagram the part A is the electrolyte, the part part B is the electrolyte gel when is fresh and the part C is the surface of the skin
Now as the electrolyte gel start to dry out the resistance of the gel begins to increase and this starts to limit the flow of current . Now when the gel is then completely dried out the resistance of the gel then increases to infinity and this in turn cut off flow of current.
The diagram illustrating this is shown on the second uploaded image
