Quiz zum Vortrag
What is the “mass defect” of the nucleus?
- The difference between the sum of the mass of the constituents of the nuclei and the mass of the nuclei
- The loss of mass from collisions of different nuclei
- The missing mass from nuclei when they are on their own
- The amount of force required to break a nucleus apart
- The binding energy required to split the electrons from the nucleus in an atom
Which fundamental force keeps nucleons together?
- The strong nuclear force
- The weak nuclear force
- The electromagnetic force
- The gravitational force
- None of these forces
Which of the following forces are in competency with each other in a nucleus?
- The strong nuclear force and repulsive electromagnetic force
- The weak nuclear force and attractive electromagnetic forces
- The electromagnetic forces and gravitational forces
- The repulsive spring forces and gravitational forces
- The electromagnetic and frictional forces
What is the difference between fission and fusion?
- Fission is the breaking of a heavy unstable nucleon into lighter nuclei. Fusion is the binding of two lighter nuclei into a more stable nuclei. In both processes energy is released.
- Fission is the breaking apart of molecules; fusion is the binding of nucleons. Both processes release energy.
- Fission is the breaking apart of molecules; fusion is the binding of molecules. In both processes energy is released.
- Fusion is the breaking of a heavy unstable nucleon into lighter nuclei. Fission is the binding of two lighter nuclei into a more stable nuclei. In both processes energy is released.
- Fission is the binding of molecules; fusion is the breaking apart of molecules. In both processes energy is released.
Why does the binding energy per nucleon begin decreasing as a nucleus grows large (e.g., beyond iron)?
- The attractive strong force is short range but the electromagnetic force is long range hence for larger nuclei the electromagnetic force starts to dominate.
- The repulsive strong force is long range but the electromagnetic force is short range hence for larger nuclei the strong force begins to dominate.
- The weak nuclear force is weaker than the electromagnetic force for larger nuclei.
- The weak nuclear force is short range but the electromagnetic force is long range hence for larger nuclei the electromagnetic force starts to dominate.
- The binding energy depends inversely on the number of nucleons.
