The advantage of a synchronous orbit is that the satellite can: fly over the entire earth transmit over the entire earth receive
dsp73

Answer:

<u>receive continuous signals from a ground transmitter</u>

Explanation:

Remember a <u>synchronous orbit is synchronous in the sense that it has equal rotational period to the body orbiting having the same direction of rotation as that body</u>. An example of this is the Moon and the planet earth.

Thus it allows continuous signals to be sent from a ground transmitter and received by a space object.

A series RLC circuit is driven by a 1.0-kHz oscillator. The circuit parameters are Vms = 12 V, L = 5.0 mH, C= 4.0 uF, and R=102.
alexgriva [62]

Answer:

C) 12.3 volts

Explanation:

f = frequency of oscillator = 1 kHz = 1000 Hz

V_{rms} = 12 Volts

L = Inductance of Inductor = 5 mH = 0.005 H

X_{L} = Inductive reactance

Inductive reactance is given as

X_{L} = 2\pi fL

X_{L} = 2(3.14) (1000)(0.005)

X_{L} = 31.4

X_{C} = Capacitive reactance

Capacitive reactance is given as

X_{C}=\frac{1}{2\pi fC}

X_{C}=\frac{1}{2(3.14)(1000)(4\times 10^{-6})}

X_{C} = 39.8

Impedance of the circuit is given as

z = \sqrt{R^{2}+(X_{L} - X_{C})^{2}}

z = \sqrt{102^{2}+(31.4 - 39.8)^{2}}

z = 102.35

Rms Current flowing is given as

i = \frac{V_{rms}}{z}

i = \frac{12}{102.35}

i = 0.12 A

Rms potential difference across the resistor is given as

V = i R

V = (0.12) (102)

V = 12.3 volts
