Answer:
Z = 138.5 Ω
Explanation:
In a series RLC circuit the impedance is
Z = ![\sqrt{R^2 + ( X_L - X_C)^2 }](https://tex.z-dn.net/?f=%5Csqrt%7BR%5E2%20%2B%20%28%20X_L%20-%20X_C%29%5E2%20%7D)
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

True, scientists often talk to each other to figure out if their results were similar and what they could have done better.
Although, talking to other scientists does have risks, other scientists could copy your work and further better it.
So, your final answer is TRUE, sorry for the long answer, I needed to have a word count about 20 characters and then I got carried away! lol
