Answer:
An electrical cell is a device used to generate electricity, or to make chemical reactions by applying electricity.
Answer:
If I understand correctly. Line B is parallel to the circle. Also, the angle is less than 90.
- The size of the circle determines.
- The diameter should not be fixed either.
Chain reactions
Neutrons released in a fission reaction can strike other nuclei and cause chain reactions
Explanation:
In nuclear fission reactions, the heavier atoms split into into lighter atoms, releasing neutrons at high velocity in the process. The neutrons hit other heavier atoms in the vicinity and split them too releasing more neutrons. This continuation is called chain reaction. The more the released neutrons the higher the rate of chain reactions. This causes too much energy to be produced at a go until an enormous explosion occurs (like in bombs).
In controlled nuclear fission such as in nuclear reactors, the number of neutrons is controlled so as to prevent the reactor from exploding. A wall that absorbs excess neutrons is used to control the number of chain reactions to prevent the release of too much energy at once.

Answer:
True Explosion in antarctic sea ice levels may cause another ice age.
Explanation:
True
Using computer models, the studies show that a rise in sea ice may significantly change the ocean's circulation, ultimately resulting in a reversed greenhouse effect as ocean carbon dioxide rises and air levels decrease.
Some scientists at the University of Chicago said their analysis shows how the rise of Antarctic sea ice in cold climate could cause a cascade of shifts that could lead to turning the global climate towards glacial periods,
