Physics 107 - Making Comparisons
|
Learning Goals:
Part I - Radiation Count Rate
You will be measuring the rate at which radioactive particles are
measured close to an alpha-emitter. The radioactive particles are
emitted randomly, so you will need to use the statistical
techniques learned so far to come up with a measurement of the
average count rate (in counts/minute) and the uncertainty in that
count rate.
Part II
Part III
Marking Scheme
1 mark for writing down a plan for 20 minutes of data-taking.
3 marks for measuring the radiation count rate (including
histogram, mean, standard deviation, and uncertainty in the mean).
1 mark for writing down a plan to re-measure pendulum periods in
25 minutes.
3 marks for high-precision measurments of pendulum period,
including t-comparisons of different angles
2 marks for scatter plot of period versus angle
3 marks for second measurement of count rate and analysis
1 mark for conclusion on whether the count rate has become smaller
