How do you multyply integers?
when you have a negative times a negative it will equal a positive but when you have a negative times a positive it will equal a negative no matter what!
What is the physical meaning of charge density on lines or on areas?
Every object consists of a certain amount of positive charge and a certain amount of negative charge. For neutral objects, the amount of each type of charge is equal in every tiny, or infinitesimal, portion of the object. If the object has the shape of a line, the amount of positive charge in each tiny segment of length along the line is equal to the amount of negative charge in each tiny segment of length. For a neutral three-dimensional object, such as a cube, the amount of negative charge in each small volume element of the total volume of the cube is equal to the amount of positive charge in each small volume element. All neutral objects have a charge density of zero throughout their volumes despite the fact that they have charge. The charge density describes the amount of excess charge per given region of space. For objects that are not neutral, then, the charge density is either positive or negative. A positive charge density expresses the fact that an object has a given amount of positive charge more than it has negative charge in a specific region of space. Likewise, a negative charge density means the object has a given amount of negative charge more than positive charge for a given region of space. For a line of charge, the charge density is expressed as Coulombs per meter when using SI units. For a two-dimensional object, such as a disk, the charge density using SI units is Coulombs per (meter^2). For objects that have uniform excess charge throughout their volume, the charge density is expressed as the total amount of excess charge on the body divided by the total length/ area/ volume of the body. For objects that have nonuniform charge excesses, the charge density must be expressed as a function of position (and possibly, time) within the object.
Does a negative divided by a negative equal a negative?
It is a positive.
Does a negative plus a negative equal a postive?
No, a negative plus a negative is a negative
Is negative 4.3 equal to negative 4.03?
No. They are different numbers, so they are not equal.
How can an object have a neutral charge if part of the object has a positive and a negative charge?
If the positive and negative charges are equal, then the object has a 'net' neutral charge.
Is the charge of a electron always equal to the charge on a neutron?
The charge on an electron is never equal to the charge on a neutron. An electron carries one negative charge and a neutron has no net charge.
When ions having a positive charge form bonds with ions having a negative charge the charge on the resulting compound is what?
The charge is 0 if the positive and negative charges were equal
What will be the charge of an atom be if it has an equal number of positive and negative charges?
Neutral - the atom will have no charge.
What objects with equal amounts of positive and negative charge are said to be electrically?
An object with equal amounts of positive and negative charge is electrically neutral.
Will an atom have a negative charge if it has more protons than nuetrons?
The neutrons do not affect the charge of an atom. The positive charge is on the proton the equal but negative charge is on the electron.If an atom has more electrons than protons it will have an overall negative charge.
Why is every atoms charge 0?
you equal negative and positives.
The charge on Neutron is equal to the charge on aton?
Yes and no - an atom has no charge - it is neutral because it contains equal numbers of positive and negative charges. A neutron has no charge at all, ever.
Electrons carries a positive or negative charge?
Yes, they have a negative charge. Protons have a positive charge and neutrons have no charge, they are neutral.
How does the amount of positive charge on a proton compare with the amount of negative charge on a electron?
equal but opposite
Matter that has an equal amount of positive and negative charge are known as?
Neutral
Which charge is the largest proton or electron?
Protons have positive charge, electrons have negative charge. Both these charges are equal and opposite.
