Question

a) Einstein discovered a quantity in his equations equal to m0c2. He called this quantity
1. Relativistic Gravitational Potential Energy.
2. Relativistic Kinetic Energy.
3. Foundational Energy.
4. Rest Mass Energy.

b) In the Theory of Special Relativity, the momentum of a massless particle is equal to which of the following?
1. E/c2
2. E/c
3. m0c2
4. E2c2

c) When energy is released in a nuclear reaction, which of the following is true?
1. There is the same amount of mass as before.
2. There is more total mass than before.
3. There is less total mass than before.
4. Nuclear fission processes leave less mass, nuclear fusion processes create more mass.

Explanation / Answer

a.) option 4 is correct

E = mc^2

b.) option 2 is correct

E^2 - (Pc)^2 = (mC^2)^2

m=0

E^2 = (Pc)^2

P = E/C

c.)option 4 is correct

Nuclear fission processes leave less mass, nuclear fusion processes create more mass.
