What is the primary mechanism responsible for energy release in nuclear fusion reactions?

  1. Electromagnetic repulsion

  2. Strong nuclear force

  3. Weak nuclear force

  4. Gravitational attraction


Correct Option: B
Explanation:

The strong nuclear force, also known as the strong interaction, is responsible for binding nucleons together in atomic nuclei. During nuclear fusion, the strong force overcomes the electrostatic repulsion between positively charged nuclei, allowing them to merge and release significant amounts of energy.

In a nuclear fission reaction, what is the primary mechanism responsible for splitting the nucleus?

  1. Electromagnetic repulsion

  2. Strong nuclear force

  3. Weak nuclear force

  4. Gravitational attraction


Correct Option: A
Explanation:

Electromagnetic repulsion between positively charged protons within the nucleus is the primary mechanism responsible for splitting the nucleus in nuclear fission. When the repulsive force overcomes the strong nuclear force, the nucleus becomes unstable and breaks apart into smaller nuclei, releasing energy in the process.

What is the name of the process in which a nucleus captures a neutron and undergoes a transformation?

  1. Nuclear fusion

  2. Nuclear fission

  3. Neutron capture

  4. Beta decay


Correct Option: C
Explanation:

Neutron capture is the process in which a nucleus absorbs a neutron, resulting in the formation of a heavier nucleus. This process can lead to the formation of radioactive isotopes and is important in various nuclear reactions, including stellar nucleosynthesis and nuclear power generation.

What is the name of the process in which a nucleus emits an alpha particle?

  1. Nuclear fusion

  2. Nuclear fission

  3. Alpha decay

  4. Beta decay


Correct Option: C
Explanation:

Alpha decay is the process in which a nucleus emits an alpha particle, which consists of two protons and two neutrons. This process is common among heavy, unstable nuclei and is a form of radioactive decay.

What is the name of the process in which a nucleus emits a beta particle?

  1. Nuclear fusion

  2. Nuclear fission

  3. Alpha decay

  4. Beta decay


Correct Option: D
Explanation:

Beta decay is the process in which a nucleus emits a beta particle, which can be either an electron or a positron. This process is common among unstable nuclei and is a form of radioactive decay.

What is the name of the process in which a nucleus emits a gamma ray?

  1. Nuclear fusion

  2. Nuclear fission

  3. Alpha decay

  4. Gamma decay


Correct Option: D
Explanation:

Gamma decay is the process in which a nucleus emits a gamma ray, which is a high-energy photon. This process is common among excited nuclei and is a form of radioactive decay.

What is the name of the process in which a nucleus scatters an incoming particle?

  1. Nuclear fusion

  2. Nuclear fission

  3. Elastic scattering

  4. Inelastic scattering


Correct Option: C
Explanation:

Elastic scattering is the process in which a nucleus scatters an incoming particle without changing its energy. This type of scattering conserves both energy and momentum.

What is the name of the process in which a nucleus scatters an incoming particle and changes its energy?

  1. Nuclear fusion

  2. Nuclear fission

  3. Elastic scattering

  4. Inelastic scattering


Correct Option: D
Explanation:

Inelastic scattering is the process in which a nucleus scatters an incoming particle and changes its energy. This type of scattering does not conserve energy and momentum.

What is the name of the phenomenon in which the scattering cross-section of a nucleus is much larger than its physical size?

  1. Resonance scattering

  2. Rutherford scattering

  3. Compton scattering

  4. Rayleigh scattering


Correct Option: A
Explanation:

Resonance scattering is the phenomenon in which the scattering cross-section of a nucleus is much larger than its physical size. This occurs when the incoming particle has an energy that matches the energy of an excited state of the nucleus.

What is the name of the phenomenon in which the scattering cross-section of a nucleus is proportional to the square of the atomic number?

  1. Resonance scattering

  2. Rutherford scattering

  3. Compton scattering

  4. Rayleigh scattering


Correct Option: B
Explanation:

Rutherford scattering is the phenomenon in which the scattering cross-section of a nucleus is proportional to the square of the atomic number. This is due to the electrostatic repulsion between the positively charged nucleus and the positively charged incoming particle.

What is the name of the phenomenon in which the scattering cross-section of a nucleus is proportional to the wavelength of the incoming particle?

  1. Resonance scattering

  2. Rutherford scattering

  3. Compton scattering

  4. Rayleigh scattering


Correct Option: C
Explanation:

Compton scattering is the phenomenon in which the scattering cross-section of a nucleus is proportional to the wavelength of the incoming particle. This is due to the interaction between the incoming photon and the electrons in the nucleus.

What is the name of the phenomenon in which the scattering cross-section of a nucleus is proportional to the fourth power of the wavelength of the incoming particle?

  1. Resonance scattering

  2. Rutherford scattering

  3. Compton scattering

  4. Rayleigh scattering


Correct Option: D
Explanation:

Rayleigh scattering is the phenomenon in which the scattering cross-section of a nucleus is proportional to the fourth power of the wavelength of the incoming particle. This is due to the interaction between the incoming photon and the electric field of the nucleus.

What is the name of the technique used to study the structure of nuclei by scattering high-energy electrons from them?

  1. Electron scattering

  2. Neutron scattering

  3. X-ray scattering

  4. Gamma-ray scattering


Correct Option: A
Explanation:

Electron scattering is a technique used to study the structure of nuclei by scattering high-energy electrons from them. This technique allows researchers to probe the distribution of protons and neutrons within the nucleus.

  1. Electron scattering

  2. Neutron scattering

  3. X-ray scattering

  4. Gamma-ray scattering


Correct Option: B
Explanation:

Neutron scattering is a technique used to study the structure of nuclei by scattering neutrons from them. This technique allows researchers to probe the vibrational and rotational modes of the nucleus.

What is the name of the technique used to study the structure of nuclei by scattering X-rays from them?
