Submit quiz
Once you submit, you will no longer be able to change your answers. Are you sure you want to submit the quiz?
1.
A mass change of 1.0 × 10−30 kg releases energy of
3.0 × 10−22 J
9.0 × 10−14 J
9.0 × 10−47 J
1.0 × 10−30 J
2.
1 u is equivalent to approximately
931.5 eV
931.5 keV
931.5 GeV
931.5 MeV
3.
In a nuclear reaction, the products have less total rest mass than the reactants. This means
energy is released
energy must be supplied
no energy changes occur
charge is not conserved
4.
A gamma-ray photon creates an electron-positron pair. The minimum photon energy is about
0.51 MeV
931.5 MeV
1.02 MeV
0.26 MeV
5.
A graph of ΔE against Δm is plotted. The gradient is
c
h
1/c2
c2
6.
Which statement is correct?
Total mass-energy is conserved in a nuclear reaction
Total rest mass is always conserved in a nuclear reaction
Energy is created from nothing in fission
Mass cannot be converted to energy
