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
How does a star form?
Contraction of a large amount of gas into heavier element by way of nuclear fusion
Contraction of a large amount of gas into heavier element by way of nuclear fission
Expansion of large amount of gas by nuclear fission
Expansion of large amount of gas by nuclear fusion
Which are real life uses of nuclear phenomena?
nuclear power plant
radiation therapy
smoke detectors
stars shining
erupting volcano
