In 1st year you experimented with some properties of resistor and capacitor (RC) networks. In this experiment, we use a resistor and capacitor connected to form low-pass filters.

What is the cutoff frequency, if we pass our signal through a RC filter with 10kΩ resistor and 0.22μF capacitor? Give your answer in Hz to 2 significant figures.

The efficiency of an antenna increases with its size. Ideally, an antenna should be several wavelengths in size. An antenna much smaller than a wavelength will be very inefficient, and will radiate only a small fraction of the power applied to it.

Which of the following multiple choice options gives the correct net current passing through a circle of radius s<R?

Looking at the distribution of the pull values from the previous fit, you should see a trend in terms of if they are positive or negative depending on the temperature. Pick the correct statement below.

Now edit your python file to use the data set PHS2062_gas_short_2_data.csv instead. This data was obtained my making new measurements after a careful evaluation of the measurement uncertainties. Select the statement(s) below that you agree with. Marking is set up such that selecting a correct result gives a positive mark, while not selecting a correct result will give a negative mark. Selecting all options gives zero marks. Selecting zero options gives zero marks.

Using the python script PHS2062_gas_fit.py perform a fit to the datafile PHS2062_gas_short_data.csv as on the last page of the book on Goodness of Fit. From the fit, select which of the following statements that you agree with.

It is important that you wear appropriate footwear in the 2nd floor physics laboratories. You will not be allowed to attend a class if you are wearing:
