Does pressure change faster as you move horizontally or vertically? explain reasoning

ANTONII [103]3 years ago

3 0

Answer:

Vertically

Explanation:

Pressure changes faster as we move vertically because as we go to the height from the surface of the earth. The density of air becomes lesser in comparison with the surface of the earth. So, as we move vertically pressure moves faster than in comparison with the vertical movement.

The best example that describes the above statement is the hill station.

The energy flow per unit time per unit area (S) of an electromagnetic wave has an average value of 440 mW/m2. The maximum value

mafiozo [28]

To solve this problem we will proceed to convert the Intensity Units given to a normal system, that is, to standardize their value. Later we will use the value of the electric field according to the RMS electric field, to find it.

Finally the magnetic field would be given based on the previously found electric field, depending on the speed of light:

The value of the intensity is:

$I = 440mW/m^2 = 0.440W/m^2$

The maximum value of the electric field is,

$E_{max} = \sqrt{2}E_{rms}$

$E_{max} = \sqrt{2}\sqrt{Ic\mu_0}$

Where,

I = Intensity,

$\mu$ = Permeability constant

c = Speed of light

Replacing,

$E_{max} = \sqrt{2}\sqrt{(0.440)(3*10^8)(4\pi*10^{-7})}$

$E_{max} = 18.2V/m$

The maximum value of the magnetic field is,

$B_{max} = \frac{E_{max}}{c}$

$B_{max} = \frac{18.2}{3*10^8}$

$B_{max} = 6.06*10^{-8}T$

Therefore the maximum magnetic field is $7.10*10^{-8}T$

djyliett [7]

Hi Pupil Here is your answer ::

➡➡➡➡➡➡➡➡➡➡➡➡➡

1 The shape of the Body

Example : The shape of the ball lying on a floor can be changed by pressing it.

2 Direction of the Body

Example : The direction of motion of moving ball can be changed by hitting it with a bat.

3 The speed of the Body

Example : A ball at rest can be set in motion if force is applied only

4. Size of the Body

Example : The length of a spring tied and on one end can be increased by pulling it.
