Answer:
seasons experienced by the northern and southern hemisphere always differ by six months when it is summer in the northern hemisphere, it is winter in the southern hemisphere
Explanation:
Answer:
0.03127 fraction of a sample of this nuclide would remain after 12.5 hrs.
Explanation:
Initial mass of the isotope =
Time taken by the sample, t = 12.5 hour
Formula used :
where,
= initial mass of isotope
N = mass of the parent isotope left after the time, (t)
= half life of the isotope = 2.5 hour
= rate constant
Now put all the given values in this formula, we get
0.03127 fraction of a sample of this nuclide would remain after 12.5 hrs.
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:
It means <span>a substance formed by chemical union of 2 or more elements or ingredients in definite proportion by weight.</span>
