Answer:
Z = 138.5 Ω
Explanation:
In a series RLC circuit the impedance is
Z =
the capacitive impedance is
X_C = 1 / wC
the inductive impedance is
X_L = wL
in this exercise indicate that C = 50 10⁻³ F, L = 0.3 H and the frequency is f=60 Hz
angular velocity and frequency are related
w = 2π f
w = 2π 60
w = 376.99 rad / s
let's calculate
Z =
Z =
Z = √19179.6
Z = 138.5 Ω
Answer:
formula: A mass m suspended by a wire of length L is a simple pendulum and undergoes simple harmonic motion for amplitudes less than about 15º. The period of a simple pendulum is T=2π√Lg T = 2 π L g , where L is the length of the string and g is the acceleration due to gravity.
Answer:
It should be 1 meter, but I'm no scientist.
Explanation: IDK
Answer:
I think it's Answer A. Because the ball eventually came to a stop, infering that the energy was used up. Hope this helped! :)
