Air pressure is gravity pulling down on air molecules. a. True b. False

1 answer:

8 0

<span>Air pressure is gravity pulling down on air molecules. Like us, air has also mass and the pressure is brought down by the earth’s gravity causing an increase in weight exerted on you as you descend lower into the atmosphere. So, as you enter into the other layers of atmosphere above the troposphere, the air pressure starts to decrease. <span>Below the atmosphere is the hydrosphere. This is where all liquid forms are located. And since the seawater has a greater mass than air, it has the greatest pressure. The answer is true.</span></span>

What is the relation between electric intensity dn flux

Zepler [3.9K]

The relation between the electric intensity and electric flux is that the electric flux is equal to the scalar product of electric flux intensity and vector area.

<h3>What is the relation between electric intensity and flux?</h3>

The electric field is the field, which is surrounded by the electric charged. The electric field is the electric force per unit charge.

The intensity of this electric field is the number of electric field lines which are pass perpendicular to the unit element of fixed area.
The flux of this electric field is the number of electric field lines which are pass normally to the fixed area.

The electric flux can be given as,

$d\phi =\vec E \;dA\cos \theta$

When angle is zero,

$d\phi =\vec E \;dA\times1\\d\phi =\vec E \;dA$

Thus, the total flux is,

$\phi=\oint_{}^{}\vec E.d\vec A$

Thus, the relation between the electric intensity and electric flux is that the electric flux is equal to the scalar product of electric flux intensity and vector area.
