In nuclear physics, a cross section is essentially the probability that a nucleus will interact with something. An isotope with a high fission cross section, like U-235, is very likely to absorb a thermal (slow) neutron and undergo fission. The cross section has units of area, usually cm2, which is where the name comes from. When the cross section is multiplied by the neutron flux, the product is the fission rate, or number of fissions per second.

What four things can determine an object's resistance?
nature of material(resistivity),length of material,area of crosssection&temprature
How can the rate of reaction be slowed down in a nuclear fission reactor?
By inserting the control rods which absorb neutrons using boron, cadmium, or other material with a large neutron capture crosssection. If the reactor should begin to run out of control the SCRAM system will suddenly insert large amounts of neutron absorbing material, instantly stopping the neutron chain reaction.
Where do you get nuclear fission?
You get nuclear fission in:nuclear fission reactorsatomic fission bombs
What do control rods in a reactor contain?
The 2 most common materials are cadmium or boron, due to their large neutron absorption crosssection.
What is the crosssection perpendicular to the base of a triangle?
A triangle does not have a cross-section but the perpendicular line of a right angle triangle meets the base at 90 degrees.
What is fission product?
Fission products are the fragments resulting from the fission of heavy nuclids during nuclear fission process
For a sustainable fission reaction each fission must produce exactly additional fission reaction(s).?
A stable nuclear fission reaction will be sustained if every fission produces one additional fission reaction.
The splitting of a heavy nucleus is called?
nuclear fission
Is fission a particle?
No. Fission is a process.
What is the splitting of an atoms nucleus into two smaller nuclei is called?
nuclear fission
Tapeworms can reproduce by fission or budding?
Fission
What is a fission equation?
Nuclear Fission has not an equation.
