A circuit contains a resistor, an inductor, and a capacitor. When an AC voltage is applied across the circuit, the impedance of
1 answer:
Answer:
The impedance of the circuit depends on the angular frequency of the voltage source.
Explanation:
- In a electric circuit, the magnitude of the impedance, is given by the following expression:
where R = Resistance
Xl = Inductive reactance = ω*L
Xc = Capacitive Reactance = 1/ωC
and ω = angular frequency of the voltage source.
- So, it can be seen that the impedance depends on the value of the constants R,L and C, and on the angular frequency ω.

Answer:
The distance between the station A and B will be:
Explanation:
Let's find the distance that the train traveled during 60 seconds.
We know that starts from rest (v(0)=0) and the acceleration is 0.6 m/s², so the distance will be:
Now, we need to find the distance after 25 min at a constant speed. To get it, we need to find the speed at the end of the first distance.
Then the second distance will be:
The final distance is calculated whit the decelerate value:
The final velocity is zero because it rests at station B. The initial velocity will be v(1).
Therefore, the distance between the station A and B will be:
