Speed - the rate of change of position. 
<span>Speed = Distance / Time. </span>
<span>Common units utilized for speed are meters per second (m/s) or miles per hour (mi/h). </span>

<span>Velocity - the rate of change of position. </span>
<span>Velocity = Displacement / Time. </span>
<span>Common units utilized for velocity are meters per second (m/s) or miles per hour (mi/h). </span>

<span>The main difference between speed and velocity is that speed is a scalar quantity (does not depend on direction) whereas velocity is a vector quantity (which does depend on direction). </span>

<span>Acceleration - Change of velocity over time. </span>
<span>Force = Mass x Acceleration. </span>
<span>Acceleration = Force / Mass. </span>
<span>Common used units of acceleration are meters per second squared (m/s^2). </span>

<span>Hope that helped :)</span>

Over the time interval after a difference in potential is applied between the ends of a wire, what would happen to the drift vel
Dmitrij [34]

The the drift velocity of the electrons is determined by atom vibrations in the crystal lattice.

<h3>How to explain the information?</h3>

Assume we could increase the average time between collisions in a typical metal to get to a limit of zero resistance. The free electrons would therefore be continuously accelerated by a constant applied voltage, according to the classical paradigm of conduction. Both the current and the drift speed would gradually pick up over time.

Although it is not the scenario implied by the question, it is possible to switch to zero resistance by using a superconducting wire instead of the usual metal. In this scenario, the maximum current is constrained, the drift velocity of the electrons is determined by atom vibrations in the crystal lattice, and it is difficult to produce a potential difference across the superconductor.

Change in velocity from 2 to -3
Alecsey [184]

Velocity units =m/s

Acceleration is the rate of change of velocity

a =timechange in velocity

Therefore SI units of acceleration is ms−1/s=s2m

1) For a positive point charge, the lines radiate ………. . While, for a negative point charge, the lines converge …………. .
ch4aika [34]

Answer:

For a positive point charge, the lines radiate <u>outwards</u>, while for a negative point charge, the lines converge<u> inwards.</u>

Explanation:

A single point charges produces an electric field which has a radial shape.The sign of a charge determines the the direction of the field. In Positive charge have the direction of field is out of the charge and for negative charge, the direction of field is towards the charge.This behavior is in relation to how a positive test charge will experience in a field.
