Quiz zum Vortrag
In the equation N(t) = N₀e^(-λt), what does N₀ stand for?
- The initial amount of radioactive material
- The final amount of radioactive material
- The decay rate of the radioactive material
- The difference between the initial and final amount of radioactive material
- None of the other choices
What is the half life of a radioactive material?
- The time it takes for half the radioactive material to decay
- Half life is another name for the inverse decay rate of the material
- Half the time of decay of all the material
- The time required to half the entirety of the material, radioactive and otherwise
- The time it takes to remove all the radioactive material
Which physical equation is the main equation used in a mass spectrometer?
- The equation for the radius of charged particles moving in a cyclotron: r = vBq/m
- Newton’s 3rd law
- The Einstein's equation: E = mc²
- The force exerted on a charged particle moving a magnetic field: f = qvBsinθ
- The half life equation: t₀.₅ = ln(2)/λ
Once the arrival locations of the ions in the detector of a mass spectrometer is known what information regarding the ions can be determined?
- Their charge to mass ratio
- The size of the ion
- The shape of the ion
- The mass of the ions
- The charge of the ions
How is the radioactive decay rate λ determined from a graph?
- The negative slope of a semi-log plot of the amount of radioactive material versus time
- The intercept of a semi-log plot of remaining radioactive material versus time
- The slope of a semi-log plot of half-life versus time
- The slope of a semi-log plot of half-life versus decay rate
- The negative slope of the tangent to the graph of the radioactive material vs time at half life
