(a) Use a CAD tool to plot the signal v(t) over three cycles of
the fundamental frequency.
(b) On a separate CAD plot, plot the fundamental and each of the
harmonics overlaid on one plot. Please include a legend in this
plot indicating each harmonic.
(c) Use a CAD tool...

A circuit is constructed with an AC generator, a resistor,
capacitor and inductor as shown. The generator voltage varies in
time as ε =Va - Vb = εmsinωt,
where εm = 120 V and ω = 651 radians/second. The values
for the remaining circuit components are: R = 97 Ω, L = 114.8 mH,
and C = 11.9μF.
3)
What is φ, the phase angle between the generator voltage and the
current in this circuit. The phase φ is defined...

1.). Two sinusoidal waves are moving through a medium in the
same direction, both having amplitudes of 4.00 cm, a wavelength of
3.50 m, and a period of 6.25 s, but one has a phase shift of an
angle φ. What is the phase shift (in rad) if the resultant
wave has an amplitude of 4.00 cm? Hint: Use the trig identity
2.). Consider two sinusoidal sine waves traveling along a
string, modeled as
y1(x, t) = (0.2 m)sin[(6 m−1)x...
