Weak interaction is a lecture and an article about the application of laboratory and theoretical physics to astronomical phenomena.

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

To improve your score, read and study the lecture, the links contained within, listed under See also, External links, and in the {{charge ontology}} and {{radiation astronomy resources}} templates. 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.

Suggestion: 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!

For standard basis, or unit, vectors (i, j, k) and vector components of a (ax, ay, az), what are the right ascension, declination, and value of a?

 if the x-axis is the longitude of the Greenwich meridian, and ax equals ay, then RA equals 6h if the x-axis is the longitude of the Greenwich meridian, and ax equals ay, then RA equals 3h the value of a is given by ${\displaystyle a={\sqrt {a_{x}^{2}+a_{y}^{2}+a_{z}^{2}}}}$ if ax equals ay equals az, then the declination is -45° if ax equals ay equals az, then the declination is +45°

17 Which of the following are associated with the envelope of the polarization current density?

## Hypotheses

1. The weak interaction is also a function of the number of interferences (very few) and the distance exponent.
