Homework Statement
In the circuit shown in the following figure(Figure 1) the capacitor has capacitance 20 microF and is initially uncharged. The resistor R_0 has resistance 12 Ohms . An emf of 90.0V is added in series with the capacitor and the resistor. The emf is placed between the...
Ah, so, since the frequency of the observer is 11% greater than the frequency of the source, (f_s)/(f_o) = 1/1.11, correct? Then, just solve for beta and report the absolute value of it (wikipedia is telling me that beta is the velocity of the observer/speed of light)?
