Question 1.
What does Einstein's equation E=mc² represent?
Show hintHide hint
Think about how energy and mass can transform into each other.
Question 2.
What is a mass defect?
Show hintHide hint
Consider what happens when nucleons come together to form a nucleus.
3Question 3.
What is the formula that shows mass-energy equivalence?
- E=mc²
- E=mv²
- E=mgh
Show hintHide hint
Recall the famous equation attributed to Einstein.
4Question 4.
True or False: Binding energy is the energy needed to break apart nucleons in a nucleus.
- True
- False
Show hintHide hint
Consider what happens when nucleons are separated.
Question 5.
Calculate the binding energy of a carbon nucleus composed of 6 protons and 6 neutrons. If the total mass of the nucleus is 12.011 u and the mass defect is 0.012 u. Use 1 u = 931.5 MeV for the energy calculation.
Show hintHide hint
Start with finding the mass defect and then apply it to the known conversion for energy.
Question 6.
Discuss how mass-energy equivalence relates to real-life nuclear applications, such as nuclear reactors.
Show hintHide hint
Think about how splitting nuclei can release energy based on mass defect.
