What is the meaning of the quality-factor q in resonance circuit, what is the amplitude of the q depend on? 4. transient state of series rc circuit (1) what is the three possible state of the series rlc circuit in the transient process (2) when the circuit in the state of damped oscillation, what relationship should the r, l, c meet? what is the changing relationship of the voltage across the capacitor over time? what is the relationship between the frequency and the rlc parameter? which element controls the decay rate of voltage amplitude (time constant)? what equation of the these parameter can describe this process?

Laboratory experiments, observational field studies, and model-building are all examples of different forms of scientific investigations.  in what way do laboratory experiments primarily differ from other forms of scientific investigations?   a.  a laboratory experiment is the only accepted form of investigation within the scientific community.  b.  studies about how things behave in nature or studies involving very large objects are best answered through laboratory experiments.  c.  laboratory experiments involve the identification and control of variables.  d.  data can only be generated through laboratory experiments, not other forms of investigation.
