PLEASE PROVIDE THE LETTER WITH THE CORRECT ANSWER, THANK YOU!
What two elementary particles make up the vast majority of charged matter in the universe? Select one of the following: helium and iron photons and electrons protons and electrons protons and neutrons heat and light Which of the following describes an experiment that demonstrates that there are at least two different types of charge? Select One of the Following Rub one pair of rods made of the same material - for example, glass - with felt. Observe that the glass rods repel one another. Charge a pair each of glass and rubber rods by rubbing them with felt. Observe that that (1) the glass rods repel each other. (2) the glass rods attract the rubber rods, and (3) the rubber rods repel each other. Select two pairs of different kinds of rods - for example, glass and rubber - and rub the rods with felt. Observe that all of the rods repel one another. Select two pairs of different kinds of rods - for example, glass and rubber - and rub the rods with felt. Observe that all of the rods attract one another. Sixteen grams of oxygen contain Avogadro's number of atoms, with each atom having eight protons and eight electrons. How many coulombs, Q, of positive charge are there in the protons of 1.0kg of oxygen? Select One of the Following 4.8 times 10^7C 5.2 times 10^15C 5.4 times 10^-5C 1.7 times 10^-9C 2.0 times 10^6CExplanation / Answer
an elementary particle or fundamental particle is a particle whose substructure is unknown, thus it is unknown whether it is composed of other particles.Known elementary particles include the fundamental fermions (quarks,leptons, antiquarks, and antileptons), which generally are "matter particles" and "antimatter particles", as well as the fundamental bosons (gauge bosons and the Higgs boson), which generally are "force particles" that mediate interactionsamong fermions.A particle containing two or more elementary particles is a composite particle.
answer is (b) photons and electrons
When a piece of glass and a piece of resin—neither of which exhibit any electrical properties—are rubbed together and left with the rubbed surfaces in contact, they still exhibit no electrical properties. When separated, they attract each other.
A second piece of glass rubbed with a second piece of resin, then separated and suspended near the former pieces of glass and resin causes these phenomena:
This attraction and repulsion is an electrical phenomena, and the bodies that exhibit them are said to be electrified, or electrically charged. Bodies may be electrified in many other ways, as well as by friction. The electrical properties of the two pieces of glass are similar to each other but opposite to those of the two pieces of resin: The glass attracts what the resin repels and repels what the resin attracts.
so the answer is (a)
