What does the mass equivalence equation tell us? E=mc²

• A large amount of energy can be converted from a small amount of mass

• Gravity bends both time and space

• Gravitational waves are emitted from black holes

• Atomic nuclei emit gamma rays, beta particles, and alpha particles

How do binding forces in atomic nuclei affect the amount of energy in nuclear fission versus nuclear fusion?

• There is a larger difference in binding forces in nuclear fission.

• There is a larger difference in binding forces in nuclear fusion

• The products have a greater mass than the reactants in fission

• Binding forces do have an effect on nuclear reactions

How do solar panels work?

• Sun hits the solar panel and releases quarks

• Light hits the solar panel and releases photons

• Photons hit the solar panel and release electrons

• Electrons jump energy levels and release photons

What would you see if you viewed the double slit experiment?

• 
• 
• 
• 

When electrons move from a high level to a low energy level, which of the following statements are correct?

• Spectral lines are emitted

• Mass is converted to energy

• The photoelectric effect occurs

• Quarks combine to create subatomic particle

In order to determine the emission spectra of an unknown gas, which of the following would be most helpful?

• The emission spectra peer elements for comparison

• Discharge tubes with different concentrations of the unknown

• A periodic table indicating the groups of elements

• A table showing the wavelengths of different colors

In nuclear fission, some mass is converted to energy. This causes -

• final mass to be less than initial mass

• final mas to be more than initial mass

• final mass to be equal to initial mass
