Answer:

a. fluid

Explanation:

A fluid is any body that has the property to flow, and lacks rigidity and elasticity, and consequently yields immediately to any force tending to alter its shape and thus adopting the shape of its container. Fluids can be liquids or gases according to the different intensity of the cohesion forces existing between their molecules. In liquids, intermolecular forces allow particles to move freely, although they maintain latent bonds that cause substances in this state to have a constant or fixed volume. Gases, by contrast, consist of well-separated moving particles that collide with each other and try to disperse, such that the gases have no defined shape or volume.

Answer:

$\Phi_{E} = E\pi r^2 \omega t$

Explanation:

The electric flux is defined as the multiple of electric field and the area that the electric field passes through, such that

$\Phi_{E} = \vec{E}\vec{A}$

When calculating the electric flux, the angle between the directions of electric field and the area becomes important, especially if the angle is changing with time.

The above formula can be rewritten as follows

$\Phi_{E} = EA\cos(\theta)$

where θ is the angle between the electric field and the area of the loop. Note that, the direction of the area of the loop is perpendicular to the plane of the loop.

If the loop is rotating with constant angular velocity ω, then the angle can be written as follows

$\theta = \omega t$

At t = 0, cos(0) = 1 and the electric flux through the loop is at its maximum value.

Therefore the electric flux can be written as a function of time

$\Phi_{E} = E\pi r^2 \omega t$

sweet [91]

<span>The acceleration of the bullet is called ACTION.

</span>Formally stated, Newton's third law<span> is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.
