In a nuclear power plant, the nuclear reaction is kept from going critical by keeping the rate of reaction safe. how do the control rods figure into this?

a. the controls rods absorb the excess heat produced in the reaction.
b. the controls rods absorb excess neutrons, keeping them from causing too many uranium atoms to split too quickly.
c. the control rods provide additional neutrons to keep the reaction going.
d. the control rods absorb excess uranium atoms so that the reaction doesn't happen too quickly.

Correct answer is B

Explanation:

Control rods in Nuclear reactor:

During nuclear reaction when a heavy nucleus break up into two light nuclei that time neutron are release and these neutrons further break up other nucleus which release more neutrons which lead to a chain reaction. the nuclear reaction is kept from going critical by keeping the rate of reaction safe by using control rods. Controls rods absorb excess neutrons, keeping them from causing too many uranium atoms to split too quickly.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
