Nuclear and Particle Physics

Question 1

What is conserved during Nuclear decay?

Answer 1

Mass and Energy
Momentum 
Charge
Baryon number 
Lepton number
Strangeness

Question 2

What is Binding Energy?

Answer 2

The energy required to separate an atom into its consistent parts.

Question 3

What is the definition for Nuclear Activity?

Answer 3

The rate at which a source emits radioactive particles.

One particle emitted per second is called a Becquerel.

Question 10

What are Fermions?

Answer 10

Matter particles.

Question 11

What are baryons?

Answer 11

Particles made of 3 quarks or anti quarks.

Question 12

What are Mesons?

Answer 12

Particles made of quark and anti-quark pairs.

Question 13

What are Bosons?

Answer 13

Force carrier particles.

Question 14

What are Hadrons?

Answer 14

Made up of quarks and anti-quarks which experience a strong nuclear force.

Question 15

What is Annihilation?

Answer 15

Mass is lost and transferred into energy.

Electron + Positron = Photon

Question 16

What is Pair production?

Answer 16

Energy is transferred into mass.

Photon = Electron + Positron
