Answer:
The answer is 138.5
Explanation:
STEP 1:
The inductance per unit length of a coaxial transmission line is
L′=L<em>/ </em>I
=Ø/H
=μoI/2π In (b/a)
In this a is the radius of inner conductor
b is the radius of outer conductor
I is the coaxial transmission
μ is the magnetic permeability
Since the transmission of the charge exists in air, the value of the relative permeability is μr= I and permeability of free space is μo= 4π x 10-7 H/m . So the magnetic permeability will be
μ = μoμ r
μ =μ o(I) 4π x 10-7 H/m
L′= μoI/2π In (b/a)
= (4π x 10-7 ) (2)/2π In (10/5)
=2.77 x 10-7 H
STEP 2:
Obtain the magnetic energy stores in the magnetic field H of a volume of the coaxial transmission line containing a material with permeability μ, by using the formula given below:
Wm= 1/2 LI^2
= 1/2 (2.77x 10^-7 I^2
= 138.5 X 10^-9 I^2 J
Now we will simplify the equation
Wm= 185.5<em>I</em>^2 nJ
So, the magnetic energy stored in insulating medium is 185.5<em>I</em>^2 nJ
Answer:
plastic
Explanation:
because it is an insulator that it is a poor conductor of electricity.
<h2>
Answer:</h2>
The reaction is <u>D. endothermic</u>.
<h2>
Explanation:</h2>
Absorption or need of energy from surroundings is called endothermic process. Heat is the major common form of energy which is absorbed in this process. In this process, enthaply of reactant is less than the product.
For example, an ice cube placed in the hand for some time starts to melt and it takes energy in the form of heat from the hand. This process always requires energy because of the breaking of existing and formation of new chemical bonds.
