Answer:
The table tennis balls represent neutrons that are released when the nucleus splits and cause other nuclei to split
Explanation:
Nuclear fission is defined as the separation of a nucleus into two smaller nuclei.
It takes a neutron to set off a nuclear fission reaction. When that occurs, neutrons are released and those neutrons in turn are what set off other nuclear fissions. This is defined as a Nuclear Fission Chain Reaction. In the model, the one tennis ball that will be thrown will be modeled as the starting neutron that sets of the initial (first) fission. The mouse traps with tennis balls represent the other nucleuses waiting to be struck by the one tennis ball. Once the initial tennis ball strikes the first mouse trap, that mouse trap will release its tennis ball hitting others and continuing the cycle.
It can also be modeled as such:
Answer:
Change in plate tectonic leads to change in earth surfaces.
Plate tectonics have changed Earth’s surface over time because the earth surface is placed on these plate tectonics. Earth's outer surface is divided into various plates that slowly move over the mantle which changes Earth's surface over time by merging and separating of landmasses that turn into continents.
The movement of tectonic plates is responsible for the creation of landforms such as volcanoes and ridges. Some volcanoes are formed when the tectonic plates pull apart from one another whereas some volcanoes are produced when a tectonic plate slides over one another so we can conclude that change in plate tectonic leads to change in earth land forms.
Explanation:
Answer:
A
Explanation:
Hydrogen and chlorine need to be balanced. There is an equal amount of magnesium on each side
Fuel cells work by passing hydrogen through the anode of a fuel cell and oxygen through the cathode. On the anode site, hydrogen molecules are split into electrons and protons. They have a high efficiency therefore these fuel cells are also considered to be very clean plus a fuel cells only by-products are electricity, excess heat, and water.
Answer:
Extensive or inextinsive and either physical or chemical
