What is a Coulomb?
The coulomb is the SI unit of electrical charge. A coulomb, a unit of electrical charge, is defined as the amount of electric charge transported by a current of 1 ampere in 1 second. There are 6.241506×1018 electrons (or elementary charges) in a coulomb. A link is provided to the Wikipedia post on the coulomb.
Example of a real life situation for the integer -100?
You overdraw your bank account by 100 currency units. What is your bank balance? That is, before the bank slaps on a overdrawn penalty, an interest charge, a charge to write to you to inform you that you are overdrawn, and quite possibly, a charge to tell you that you are now even more overdrawn than you thought because of all these charges!
Offer a rationalization why the Bjerrum length is inversely porportional to temperature?
The Bjerrum length is the separation distance at which the potential electric energy of two elementary charges is equal to kB*T. The electric potential energy of two elementary charges is inversely proportional to their separation distance. Since kB*T is trivially proportional to temperature T, at a higher temperature you need to place two elementary charges closer to each other to get the electric potential energy equal to kB*T. As the separation distance between those charges is defined as the Bjerrum length, the Bjerrum length is inversely proportional to temperature.
What is the answer of David charges 15 plus 5.50 per hour to mow lawns. Ari charges 12 plus 6.25 per hour to mow lawns. In what situations is Ari's charge greater than or equal to David's charge?
If the job takes four hours or longer then Ari's charge is greater.
Find the number of miles for which the companies charges will be the same Then find that charge?
The charge per number of miles varies from one company to another while the average charge is $ 18 per mile.
What is the eletrical charge on a proton?
+1 elementary charges.
What are elementary charges in physics?
Elementary charge is the charge of a proton or an electron. It is denoted by the symbol "e". Its value is 1.602 x 10-19 C
What is the net static electric charge on a metal sphere having an excess of plus 3 elementary charges?
The net static electric charge on the metal sphere would be +3 elementary charges. This means the sphere has an excess of 3 positive charges.
What is the charge of an electon?
An alpha particle has a charge of +2 (elementary charges), since it contains two protons.
What is the charge of electons?
An alpha particle has a charge of +2 (elementary charges), since it contains two protons.
Do protons have a positive or negative charge?
The Proton has a positive charge equal to the elementary charge. This is due to its composition of a down quark and two up quarks which have charges of -1/3 the elementary charge and +2/3 the elementary charge respectively.
Are alpha particles or beta particles more highly charged?
Alpha particles are more highly charged than beta particles, as they consist of two protons and two neutrons, giving them a charge of +2. Beta particles, on the other hand, are either electrons (β-) or positrons (β+), which have a charge of -1 and +1, respectively.
What is the electonic charge of an alpha?
An alpha particle has a charge of +2 (elementary charges), since it contains two protons.
What are the electric charge rules?
Like charges repel each other, while opposite charges attract each other. Charge is conserved - total charge is constant in an isolated system. Charge is quantized - it comes in discrete units of the elementary charge (e).
What are the charges for an electron and a proton?
An electron has a negative charge of -1 elementary charge, while a proton has a positive charge of +1 elementary charge. The elementary charge is approximately equal to 1.6 x 10^-19 coulombs.
What is the charge of the electron that orbit the nucleus of an atom?
The charge of an electron is negative, specifically -1.602 x 10^-19 coulombs.
What subatomic particles are found in the nucleus of an atom what chargers do they have?
The atomic nucleus contain nucleons: protons and neutrons; these particles are formed from quarks and gluons. The proton has an electrical positive charge of 1; the neutron has not electrical charge.
