The control rods in a nuclear reactor control the reaction by:
Correct answer: A. Reducing the neutron speed
- A. Reducing the neutron speed
- B. Increasing the neutrons speed
- C. Increasing the electron speed
- D. Decreasing the electron
Explanation
Option A is correct since the neutron speed is reduced so that more neutrons are being absorbed by moving down into the reactor. Option B is incorrect since when the neutrons are increased, fear neutrons will be absorbed.Options C and D are incorrect since the reaction is controlled by neutrons of the control rods.

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
