What are 13 types of electric charge?

That's a really wonderful question, my favorite ever from this site, but you'll have to settle for a mediocre answer. I think the important proofs are experimental, because the whole theoretical framework within which things like this can be 'proved' is based on experimental results, not written on the sky. 

<span>We couldn't truthfully say that there were only two types of electrical charge unless we had some way of distinguishing between electrical charges and the 'charges' involved in other forces (gravity and the nuclear forces). Let's say that by electrical charges, we mean the sort of charges that cause forces at appreciable distances (that excludes the nuclear forces) and which can be transferred by rubbing different objects together (that pretty much excludes gravity). </span>

<span>When we say 'there are only two types of charge' what we mean is that charge can be represented by an ordinary real number, corresponding to a point on the real number line. Real numbers can be either positive or negative. For any positive, you can find a negative just big enough to cancel it and give zero. </span>

<span>What's a simple experimental version of this? You may have seen the experiment with a couple of gold leaves connected to each other. Whenever an electrical charge is deposited on the leaves, they push apart, because they share the same type of charge. You can get electrical charges to put on them from all sorts of static electricity- rubbing a rock on a wool rug, and touching the rock to the gold, etc. Now for all the many ways you can dump charge onto the gold, you can divide the whole collection into two batches, which we’ll call N and P. For any charge in batch "P", you can always get back to zero (where the leaves touch) by dribbling in bits of charge of type "N", and vice versa. So that's just like positive and negative numbers, and is the basic justification for representing the charges with positive and negative numbers. </span>

<span>You might ask (since you sound like a pretty profound asker) whether any other situation is even imaginable. Try this. Say there were some sort of charge that were represented not by numbers but by position in a plane. Say you had some "north" charge, and some "east" charge. There's no way of combining them to get back to zero- so they can't be like numbers of opposite sign. And there's no other type of charge that could be used by itself to cancel both of them- so they aren't like numbers of the same sign. There's no way to divide these planar charges into two distinct batches, where you can cancel any charge in one batch with the right amount of any charge from the other batch. So you know these charges can't be represented by real numbers. </span>

<span>In case that sounds imaginative, I can't claim credit. Nature has a lot of imagination. The 'color charges' of the strong nuclear force are pretty much like that. </span>

Molecules of two solid substances actually collide with each other to transfer energy in this method of heat transfer.
mestny [16]

Answer 1:

A) Conduction

Explanation:

Heat conduction is the movement of physical energy from a range of higher temperature to one of lower temperature by the communication of the nearby particle in the middle space. Conductivities vary for the element being famous for metallic solids, lower for nonmetallic solids, very low for liquids, and very low for gases. The best common metallic conductors are silver, copper, gold, aluminum, beryllium, and tungsten. Diamond knocks them all, and graphite beats diamond only if the heat can be forced to conduct in a direction corresponding to the crystal layers.

Answer 14:

A) Empty space

Explanation:

An atom is an essentially empty space, but empty space is often not empty. The cause it looks empty is that electrons and photons don't associate with the stuff that is there, quark and gluon track variations. It really takes energy to clear out space and make a true empty vacuum. Outer space, particularly the almost empty regions of the universe outside the environments of heavenly bodies. Vacuum, a volume of space that is actually empty of matter, such that its volatile pressure is much less than climatic pressure.

Answer 15:

C) Longitudinal waves

Explanation:

Longitudinal waves are waves in which the displacement of the mechanism is in the same direction as, or the opposing direction to, the direction of generation of the wave. Longitudinal waves are perpetually distinguished by particle motion being equal to wave motion. The two most popular classes of longitudinal waves are sound waves and p-waves from earthquakes.

Answer 16:

A) Compressing a spring.

Explanation:

Energy transformation, also termed as an energy exchange, is the method of converting energy from one of its forms into another. In physics, energy is a measure that gives the capability to make many acts think of lifting or warming an object. Most of the time, chemical energy is delivered in the form of heat, and this conversion from chemical energy to heat, or thermal energy, is named an exothermic reaction. Next, there are two main kinds of mechanical energy, kinetic energy, and potential energy.

Answer 17:

C) The ice cube is gaining energy (heat) from your hand.

Explanation:

The ice cube which was hard has changed into the liquid water because the air temperature is warmer than the freezers. Which indicates the ice bits collect heat energy from the heated air. Therefore the ice bits have enough energy to break apart into smaller particle compositions. At freezing temperature, when an ice cube hovers in water, all the time new water molecules that are around and happen to move a bit slower than normal get lost to the ice.

Answer 19:

C) Closer packed or more dense media will have higher speed of sound.

Explanation:

The speed of sound in seawater is very fast related to that in the air almost five times faster. In fact, sound travels even quicker in seawater than in freshwater. Nevertheless, the speed of sound in seawater. In water, the particles are much tighter together, and they can quickly transfer vibration energy from one particle to the next.

Answer 20:

A) From A to B is known as the wavelength and changing the pitch of the note will change its length.

Explanation:

The amount or quantity of period within two things, points, lines, etc. the state or fact of existing separate in space, as of one thing from another; remoteness. a linear amount of space: Seven miles is a distance too great to walk in an hour. Distance is a scalar quantity describing the interval in two points. It is just the measure of the interval.

Differentiate between angular displacement and linear displacement.​
Sauron [17]

Answer:

The angular displacement is not a length (not measured in meters or feet), so an angular displacement is different than a linear displacement. ... As the object rotates through the angular displacement phi, the point on the edge of the disk moves distance sa along a circular path.

Which idea did Ptolemy's model use to explain why the planets appeared to move backward as they moved in their orbits? The plane
ruslelena [56]

Answer:

The planets spun in epicycles.

Explanation:

The planets were not simply attached to a mystical sphere (“deferent”) but they were actually attached to a mini-sphere (“epicycle”) which rotated on the larger one.

I don’t know how to answer this question? Can anyone help?
VMariaS [17]

Answer:

F=ma

here F is force, m is mass and a is accelaration,

According to the question,

F=3*F= 3F

m= 1/3 of m= m/3

a= ?

so the equation becomes,

3F= m/3*a

3F*3= ma

9F=ma

F= ma/9

Therefore accelaration reduces by 1/9.

I am not very sure.
