Answer: Bases are slippery.

Explanation:

Bases and acids can be determined by the amount of hydrogen or hydroxide ions in each solution. If a solution has more hydrogen ions than hydroxide ions, it is acidic, whereas if it has more hydroxide ions than hydrogen ions, it is basic.

Using a litmus paper test for a acidic/basic solution, the paper will turn different colors. In an acidic solution, paper will turn red, but in a basic solution, paper will turn blue.

Bases, compared to acids, feel slippery on the skin because they interact with fatty acids on the skin. Comparatively, acids feel sticky.

Acids taste sour. Think of an acid like lemon juice, compared to bases, which taste bitter (blood, for example)

Why do you like the full moon ?

Answer:

<h3>The Moon brings perspective. Observing the Moon, and I mean really looking – sitting comfortably, or lying down on a patch of grass and letting her light fill your eyes, it's easy to be reminded of how ancient and everlasting the celestial bodies are. When I do this, it always puts my life into perspective.</h3>

Bare free charges do not remain stationary when close together. To illustrate this, calculate the acceleration of two isolated p

Marta_Voda [28]

Answer:

Acceleration, $a=9.91\times 10^{15}\ m/s^2$

Explanation:

It is given that,

Separation between the protons, $r=3.73\ nm=3.73\times 10^{-9}\ m$

Charge on protons, $q=1.6\times 10^{-19}\ C$

Mass of protons, $m=1.67\times 10^{-27}\ kg$

We need to find the acceleration of two isolated protons. It can be calculated by equating electric force between protons and force due to motion as :

$ma=\dfrac{kq^2}{r^2}$

$a=\dfrac{kq^2}{mr^2}$

$a=\dfrac{9\times 10^9\times (1.6\times 10^{-19})^2}{1.67\times 10^{-27}\times (3.73\times 10^{-9})^2}$

$a=9.91\times 10^{15}\ m/s^2$

So, the acceleration of two isolated protons is $9.91\times 10^{15}\ m/s^2$ . Hence, this is the required solution.
