<h2>Answer: Ion
</h2>
An ion is an atom that is electrically charged by <u>gaining or losing one or more electrons.
</u>
To understand it better:
An atom has a nucleus with electrons around it and has a neutral charge. When an electron is added or detached, this atom is electrically charged, that is, it ceases to have a neutral charge and becomes an <u>ion</u>.
In this sense, there are two types of ions:
-Anions: ions negatively charged, by the gain of electrons in the atom.
-Cations: ions positively charged, by the loss of electrons in the atom.
Answer:
°
Explanation:
Let's use the component method of vector addition:
Now, we know:
So:
Now lets calculate the magnitude of the vector B:
Finally its angle is given by:
°
Keep in mind that I added 180 to the angles of C and B to find the real angles measured from the + x axis counter-clock wise.
Explanation:
Physicists are scientist that studies physics. Physics is an aspect of physical science that seeks to understand the fundamental laws that governs how matter and energy interacts.
- Physics is a very broad science discipline and it uses the scientific method to investigate natural phenomenon.
- Applied physics deals with adapting physical solutions to provide technological solutions.
- Theoretical physics uses mathematical approaches to solve physics related problems.
- Experimental physics uses laboratory experiments for investigation.
