Assuming this is the unit 8 waves project, it's a longitudinal wave, because the energy is going left to right.
Answer:
unchanged
Explanation:
Let the voltage of the battery be V
Inductance L1 = 5 mH
Inductance L2 = 10 mH
consider resistance R of the circuit (wire, battery).
V = I R + L dI/dt
where, I is the current in the circuit and t is the time.
After few seconds of connection being made, the factor dI/dt is negligible. There is no change in the current flowing through the circuit. when inductor was just attached in the circuit, a current
Answer:
Poynting vector oscillate at a frequency of 2omega
Explanation:
This is because The poynting vector is proportional to the cross product of electric and magnetic field vectors. So Because both fields oscillate sinusoidally with frequency w, trigonometric identities show that their product is a sinusoidal function of frequency of 2w.
Answer:
The first answer is W and Z, since they appear to be a period apart. Dont know the second question. I did what I could, hope someone can answer the second.
The answer is A. <span> the state and local authorities. :) </span>
