Charges/Quiz

< Charges

Charges is a lecture and an article from the charge ontology research project on the origin and constitution of charge.

You are free to take this quiz based on charges at any time.

To improve your score, read and study the lecture, the links contained within, listed under See also, or in the charge ontology template. This should give you adequate background to get 100 %.

As a "learning by doing" resource, this quiz helps you to assess your knowledge and understanding of the information, and it is a quiz you may take over and over as a learning resource to improve your knowledge, understanding, test-taking skills, and your score.

A suggestion is to have the lecture available in a separate window.

To master the information and use only your memory while taking the quiz, try rewriting the information from more familiar points of view, or be creative with association.

Enjoy learning by doing!

Point added for a correct answer:   
Points for a wrong answer:
Ignore the questions' coefficients:

1. True or False, Charge exists in a positive and negative form.

TRUE

A composite spectrum is approximately a law over at least the ≈ 5 decade wavenumber range 10-13 m-1 < wavenumber < 10-8 m-1 and that may extend to wavenumbers.

3. True or False, The spin carried by quarks is not sufficient to account for the total spin of muons.

TRUE
FALSE

4. Which of the following are associated with electromagnetics?

angular momentum transfer
solar wind
protons
electrons
the baryon neutrino
charge neutralization

5. True or False, Like all elementary particles, the muon has a corresponding antiparticle of opposite spin but equal mass and charge (+1).

TRUE
FALSE

6. Spin-charge separation has which characteristics?

a chargon
a spinon
taking place inside solids
extremely tight confinement
neutron affinity
X-ray absorption

7. True or False, The radius of the proton is 4 percent smaller than previously estimated.

TRUE
FALSE

9. True or False, Muons inherit the high energy of the parent cosmic rays.

TRUE
FALSE

10. Complete the text:

Charged-current charged pion production is a process in which a interacts with an atomic and produces a , a charged and recoiling nuclear fragments.

Research

Hypothesis:

  1. Both a chargon and a spinon exist and can be produced from an electron.

Control groups

The findings demonstrate a statistically systematic change from the status quo or the control group.

“In the design of experiments, treatments [or special properties or characteristics] are applied to [or observed in] experimental units in the treatment group(s).[1] In comparative experiments, members of the complementary group, the control group, receive either no treatment or a standard treatment.[2]"[3]

Proof of concept

Def. a “short and/or incomplete realization of a certain method or idea to demonstrate its feasibility"[4] is called a proof of concept.

Def. evidence that demonstrates that a concept is possible is called proof of concept.

The proof-of-concept structure consists of

  1. background,
  2. procedures,
  3. findings, and
  4. interpretation.[5]
