What does the number or density of field lines on the source charge indicate

Physics

Answer:

The strength of the field

Explanation:

The density of field lines of a field (e.g. gravitational field, or electric field) indicates the strength or magnitude of the field itself. In particular:

- The regions in which the field lines are closer to each other (more dense) are the regions where the field is stronger

- The regions where the field lines are more spread apart (less dense) are the regions where the field is weaker

For example, if we consider the electric field generated by a positive point charge, the electric field is radial (outwards from the charge) and the spacing between the lines increases as we move away from the charge: this means that the strength of the field increases as we move away from the charge.

As matter changes state from gas to liquid, which of these statements is true?
alina1380 [7]
<h3><u>Answer;</u></h3>

<em>B) The particles slow down.</em>

<h3><u>Explanation;</u></h3>
  • Matter is anything that occupies space and has weight. It is classified into three states namely; <em><u>liquid, solid and gases.</u></em>
  • <u><em>Gaseous states have particles that are far apart from each other thus they move faster with few collisions in the container they are contained.</em></u> Liquid particles on the other hand are partially apart from each other as compared to solids and gases, therefore the movement of particles is slower and the collisions are more than in the case of gases.
  • Therefore,<u><em> when gases are converted to liquids, it means they will become closer to each other and thus the vibrations will increase and the movement of these particles will also be slower than in the gaseous form.</em></u>

How long does it take for a rotating object to speed up from 15.0 sto 33.3 rad/s if it has an angular acceleration of 3.45rad/s2
Gnoma [55]

Answer:

The time taken by the rotating object to speed up from 15.0 s to 33.3 rad/s is 5.30 seconds.        

Explanation:

It is given that,

Initial angular speed of the object, \omega_o=15\ rad/s

Final angular speed of the object, \omega_f=33.3\ rad/s

Angular acceleration of the object, \alpha =3.45\ rad/s^2

Angular acceleration of an object is object is defined as the change in angular velocity per unit time. It is given by :

\alpha =\dfrac{\omega_f-\omega_i}{t}

t =\dfrac{\omega_f-\omega_i}{\alpha}

t =\dfrac{33.3-15}{3.45}

t = 5.30 seconds

So, the time taken by the rotating object to speed up from 15.0 s to 33.3 rad/s is 5.30 seconds. Hence, this is the required solution.
