Answer:
A. Z = 185.87Ω
B. I = 0.16A
C. V = 1mV
D. VL = 68.8V
E. Ф = 30.59°
Explanation:
A. The impedance of a RL circuit is given by the following formula:
(1)
R: resistance of the circuit = 160-Ω
w: angular frequency = 220 rad/s
L: inductance of the circuit = 0.430H
You replace in the equation (1):
The impedance of the circuit is 185.87Ω
B. The current amplitude is:
(2)
V: voltage amplitude = 30.0V
The current amplitude is 0.16A
C. The current I is the same for each component of the circuit. Then, the voltage in the resistor is:
(3)
D. The voltage across the inductor is:
E. The phase difference is given by:
Answer:
- there is an equal and opposite force
- moving
Explanation:
When balanced forces act on an <em>object at rest</em>, the object will not move. If you push against a wall, the wall pushes back with an equal but opposite force. Neither you nor the wall will move. Forces that cause a change in the motion of an object are unbalanced forces.

Answer:
1/ K times
Explanation:
The capacitance of a parallel plate capacitor is given by
Where, A be the area of plates and d be the distance between the plates.
When a dielectric is inserted between the plates, the new capacitance is
The charge remains same.
As we know that
q = C V
The capacitance becomes KC so, to keep the charge remains same the potential difference should be 1 / K times.
V' = V / K
