Answer:
Can you plz explain what you mean by that . Maybe I can help if you give explanation.
Answer:
In this given statement , the plastic base becomes negatively charged because plastic is an insulator . And the metal cup does not become charged because metal is a conductor.
Explanation:
<u>Reason behind , why plastic base becomes negatively charged -:</u> When a plastic base is rubbed with a dry cloth in the metal trophy, electrons are shifted from one material to the other. Thus, the substance that gains electrons (which is the plastic base) becomes negatively charged. thus , the plastic is an insulator , which causes charge (negative ) by rubbing.
<u>Reason behind , why the metal cup does not become charged -:</u> The metal cup is a conductor, and the surplus charge on the metal flows to the person who charges the cup and to the ground so that it is not charged. Thus, rubbing a metal can trigger hand\finger injury because metals generate excess heat in rubbing .
All of these are body regions.
Antecubital, brachial, crural, and femoral regions are ventral/anterior appendicular body regions.
Axillary region is ventral/anterior axial body region.
Popliteal and sural body regions are dorsal/posterior appendicular body regions.
