Yes. Copper, mercury, and tin are all used to fill in cavities.
Average speed =
(distance covered during some period of time)
divided by
(length of time to cover that distance).
A.
-> the products are stable atoms with a much lower atomic number. For example, Uranium 238 commonly breaks down into strontium and xenon, both of which are stable and non-radioactive.
They are also low in quantity because of the precision involved in breaking down a large atom via neutron capture means that few fission reactions take place.
Hope I helped :)

Work = Force x Distance.
30n x 15 = 450.
450 total.
I believe the correct answer among the choices listed is option C. The four components of a controlled experiment are the independent variable, dependent variable, control, constant. A controlled experiment is a test where a researcher vary one variable at a time.<span>
