You will now examine the relationship between the number of field lines through a surface and the tangle betwcen a and e) angle between a and e. (you will need a protractor to mcasure angles.) 1. place the loop over the nails so that the number (# of field lines through surface) of field lines through it is a maximum, determine the angle between a and e. record both that angle and the number of field lines that pass through the loop. 2. rotate the loop until there is one fewer row of nails passing through it. determine the angle between a and e and record your measurement. continue in this way until θ= 180. 3. on graph paper, plot a graph of n versus o (let the number of field lines through the surface be a negative number for angles between 90 and 180.) when e and a were parallel, we called the quantity ea the electric flux through the surface. for the parallel case, we found that ea is proportional to the number of field lines through the surface. e. by what trigonometric function of θ must you multiply ea so that the product is proportional to the number of ficld lines through the area for any orientation of the surface? rewrite the quantity described above as a product of just the vectors e and a.

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 3.00 ms . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
