Understanding Mass Defect and Binding Energy

What is the composition of a helium-4 nucleus?

• Two protons and two neutrons

• Four neutrons

• Four protons

• Two protons and two electrons

What is the mass defect in the context of a helium-4 nucleus?

• The energy required to bind the nucleus

• The difference in mass between the nucleus and its individual components

• The mass of the nucleus after binding

• The total mass of protons and neutrons

Which equation is used to convert mass defect into energy?

• Planck's Equation

• Schrodinger's Equation

• Einstein's Equation (E=mc^2)

• Newton's Second Law

What is the unit of energy obtained after converting mass defect using Einstein's equation?

• Newtons

• Joules

• Electron Volts

• Watts

How is the binding energy per nucleon calculated for helium-4?

• By adding the mass of protons and neutrons

• By subtracting the mass defect from the total mass

• By dividing the total binding energy by four

• By multiplying the total binding energy by four

What is the significance of converting energy into mega electron volts?

• It simplifies the calculation of mass defect

• It provides a more convenient unit for nuclear physics

• It decreases the energy value

• It increases the energy value

What is the direct conversion factor between atomic mass units and mega electron volts?

• 1 atomic mass unit = 500 mega electron volts

• 1 atomic mass unit = 1000 mega electron volts

• 1 atomic mass unit = 931.5 mega electron volts
