The current passing through the inductor is 3.8 A. The correct option is D. 3.8 A
<h3>Energy stored in a magnetic field </h3>
From the question, we are to determine the current passing through the inductor.
From the formula, for the energy stored in a magnetic field
E = 1/2LI²
Where E is the energy
L is the inductance
and I is the current
From the given information,
E = 3.6 J
L = 0.50 H
Putting the parameters into the formula, we get
3.6 = 1/2 × 0.50 × I²
3.6 = 0.25 × I²
I² = 3.6 ÷ 0.25
I² = 14.4
I = √14.4
I = 3.7947
I ≅ 3.8 A
Hence, the current passing through the inductor is 3.8 A. The correct option is D. 3.8 A

Answer:
Nitrogen and oxygen are by far the most common; dry air is composed of about 78% nitrogen (N 2) and about 21% oxygen (O 2).
In short, Nitrogen
Let A be the 80% solution and B be the 20% solution and P be the produce solution of 70%. Va and Vb and Vp are the volumes of A and B and P respectively.
Va + 60 = Vp
0.7Vp = 0.8Va + 0.2(60)
Substituting the value of Vp from the first equation:
0.7(Va + 60) = 0.8Va + 12
30 = 0.1Va
Va = 300 gallons
Answer:
I was traveling on a train where I fell asleep. someone stole my luggage in which I had money and other essentials. when the ticket checker arrived a lady paid my fine. she helped me a lot. when I told her about being robbed she helped me and took me to the police station and I found my bag. I insisted she take the money she paid for my fine but she said that in return you too help someone."I have never found such a kind person ever since.".....
