Answer:
Distance= 3.5/31536000 cm = 1.11 × 10^(-7) cm
Explanation:
Given ;
Average speed = 3.5cm/year
Time= 1 s
Distance = speed × time
Number of seconds in a year = 31536000 sec/year
Distance = 3.5 cm/year × 1/31536000sec/year × 1 s
Distance= 3.5/31536000 cm = 1.11 × 10^(-7) cm
Capacitor in series with a 100Ω resistor and a 18.0 mH inductor will give a resonance frequency of 1000 Hz is 1.38F
Resonance Frequency of a combination of Series LCR circuit is the frequency at which resonance is achieved in a circuit.
Resonance Frequency of a combination of Series LCR circuit is given by:
f = 1 / 2π
where, f is the resonance Resonance Frequency of a combination of Series LCR circuit
L is the Inductance of the inductor
C is the capacitance of the capacitor
Given,
f = 1000Hz
L = 18.0 mH = 0.018H
R = 100Ω
C = ?
On substituting the values in the above-mentioned formula:
1000 = 1 / 2π
2π = 0.001
On solving, C = 1.38 F
Hence, the capacitance of the given capacitor is 1.38F.
