Take this Quiz: A-Level Physics: Nuclear Energy | Zestly

Question 1

Consider the binding energy per nucleon curve. Which of the following statements correctly describe the features of this curve?

Accepted Answer

The peak of the curve occurs at Iron-56, representing the most stable nucleus.

Question 2

In a nuclear reactor, a neutron induces fission of Uranium-235. Which of the following are essential components or processes to maintain a controlled chain reaction?

Accepted Answer

Using a moderator like graphite to slow down fast neutrons.

Question 3

Which of the following statements correctly describe the role of reactor safety principles?

Accepted Answer

The concrete containment shield absorbs ionizing radiation from the reactor core.

Question 4

A reaction releases 1.5 × 10^{-11} J of energy. Using $E = mc^2$, where $c = 3.0 × 10^8$ m/s, what is the equivalent mass change in kilograms?

Answer

1.67 × 10^{-28} kg

Answer

1.67 × 10^{-29} kg

Answer

5.0 × 10^{-20} kg

Answer

4.5 × 10^{6} kg

Question 5

Why does the fusion of light nuclei (e.g., Hydrogen to Helium) release energy?

Answer

The product nucleus has a higher binding energy per nucleon than the reactants.

Answer

The total mass of the product nucleus is less than the total mass of the reactants.

Answer

The fusion process requires an input of energy to overcome the strong nuclear force.

Answer

The binding energy per nucleon decreases as the mass number increases for light nuclei.
