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 .
Answer:
The ocean/water, land, weather and food.
Explanation:
The Atlantic, or Artic ocean has been melting at a faster rate quicker than before . The melted iceburgs which turn into water will flow into the oceans which will then increase the rise in hight of water in ocean and seas. Land will eventually be dried up because of the rise in temperature and the change in climate. There will be less food/crops, because we have used up most of the fresh water we had been using to grow crops for over many years. Scientists and others have considered turning the ocean's salty water into fresh water for the crops . But the process will take a while and will be a very expensive process.
