In neutral state the atom got an equal number of protons (+) and electrons (-). If you lose and electron then you will have 1 more proton than electron, so you have a +, but if you gained an electron, then you'd have one more electron than protons, so you'd get a -.
<span>Fx: carbon has 6 protons and 6 electrons. If carbon loses an electron, then the carbon atom would have 6 protons and only 5 electrons, then you'd have 6+ and 5-, which is 1 more plus and minuses, so you have C+. </span>
<span>If Carbon gained an electron, then you'd have 6+ and 7-, which is 1 more minus than pluses, so you'd have C-. </span>
<span>Last example, if you gained 2 electrons, then you'd have 6+ and 8-, which is 2 more minuses than pluses, which would give you an C-- (Also known as: C2-)</span>
Answer:
60mph=26.8224meters per second
Explanation:
We will apply the concepts related to Newton's second law. At the same time we will convert everything to the system of international units.
The values of the velocities are,
We know that the acceleration is equivalent to the change of the speed in a certain time therefore
Now applying the Newton's second law we have,
Therefore the approximate magnitude is 8516.36N
That depends on the weight, shape, size, density, and moisture content
of the cotton ball, as well as on the length, shape, thickness, and surface
texture of every little cotton fiber sticking out of it.
Now you know why we typically ignore air resistance when we work with
objects falling in gravity.
