A very long cylinder, of radius a, carries a uniform polarization P perpendicular to its axis. Find the electric field inside th
Juliette [100K]

Answer:

For electric field inside cylinder, check image 02 attached

For electric field outside cylinder, check image 03 attached

Explanation:

Let's consider the polarized cylinder as superposition of two cylinders with opposite,equal, uniform charge densities in a way shown in the figure in the "image 01"d attached ;

In general, if we have an object with polarization (P¬) , then we have to take two objects with similar shape to the system, with opposite, equal, and uniform charge densities and then we super-impose these two objects in such a way that the total dipole moment of this superimposed system is equal to the total dipole moment of original system.

Now, we can take the super- imposed system as equivalent to the original system for calculating electric field and potential.

Therefore,

For the electric field inside the cylinder, check the solution in "image 02" i attached

For the electric field outside the cylinder, check, "image 03" i attached.

bekas [8.4K]

d. lower frequencies and low energy.

Explanation:

Microwaves and infrared  waves are lower frequencies and lower energy waves.

They are both non-ionizing radiation.

  • Microwaves and infrared waves are both electromagnetic waves.
  • They do not require a material medium to be propagated in nature.
  • They have little energy because the have very low frequency.
  • They also have very long wavelengths.

A balloon contains 0.075 m^3 of
inessss [21]

Answer:

600 KPa.

Explanation:

From the question given above, the following data were obtained:

Initial volume (V1) = 0.075 m³

Final volume (V2) = 0.45 m³

Final pressure (P2) = 100 KPa

Initial pressure (P1) =?

Temperature = constant

The initial pressure can be obtained by using the Boyle's law equation as shown below:

P1V1 = P2V2

P1 × 0.075 = 100 × 0.45

P1 × 0.075 = 45

Divide both side by 0.075

P1 = 45 / 0.075

P1 = 600 KPa.

Thus, the initial pressure in the balloon is 600 KPa.

Ira Lisetskai [31]

Answer:

14J

20000J

200J

Explanation:

formula :W=FS

W:work done

F:force (N)

S:displacement moved in direction of force (m)

1) 20N×0.7m

=14J

2) 400N×50m

= 20000J

3) 10N×20m

=200J
