An AM transmitter at 27 MHz develops 10 W of carrier power into a 50- load. It is modulated by a 2-kHz sine wave between 20% and 90% modulation. Determine:
(a) Component frequencies in the AM signal.
(b) Maximum and minimum waveform voltage of the AM signal at 20% and 90% modulation. (25.3 to 37.9 V peak, 3.14 to 60.1 V peak)
(c) Sideband signal voltage and power at 20% and 90% modulation. (2.24 V, 0.1 W, 10.06 V, 2.025 W)
(d) Load current at 20% and 90% modulation. (0.451A, 0.530A)

Afaulty model rocket moves in the xy-plane (the positive y direction is vertically upward). the rocket's acceleration has components ax(t) = ? t2 and ay(t) = ? ? ? t, where ? = 2.50 m/s4 , ? = 9.00 m/s2 , and ? = 1.40 m/s3 . at t = 0 the rocket is at the origin and has velocity ~v0 = v0x ? i + v0y ? j with v0x = 1.00 m/s and v0y = 7.00 m/s. (a) calculate the velocity and position vectors as functions of time. (b) what is the maximum height reached by the rocket? (c) sketch the path of the rocket. (d) what is the horizontal displacement of the rocket when it returns to y = 0?
