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)

ok

explanation:

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
