Answer:
A) The resonance angular frequency in an L-R-C circuit is

B) The current can be found by calculating the impedance of the system.

Since
at resonance.
So, 
A close representation of the moons motion around earth is that it moves around the earth once in 27.3 days. the moons average movement is 13.2 degrees per day so around 92 per week.
Hope this helps!
<span>P = energy/t = 0.0025/1E-8 = 250000 W
I(ave) = P/A = 250000/(pi*0.425E-3^2) = 4.4056732E11 W/m^2
I(peak) = 2I(ave) = 8.8113463E11 W/m^2
Electric field E = sqrt(I(peak)*Z0) = 1.8219499E7 V/m, where
free-space impedance Z0 = sqrt(µ0/e0) = 376.73031 ohms</span>
Answer:
We know from the basic speed distance relation that

Since the car started from rest and it covered the distance between the 2 officer's in 19 minutes we have speed of the car

Which clearly exceeds the limit of
