It's called frequency, its usually stated Hertz
D is the answer I believe.
Answer:
Strong acids completely dissociate into their ions in water, while weak acids only partially dissociate. There are only a few (7) strong acids, so many people choose to memorize them. All the other acids are weak.
Explanation:
Weak acids. Explaining the term "weak acid" A weak acid is one which doesn't ionise fully when it is dissolved in water. Ethanoic acid is a typical weak acid. It reacts with water to produce hydroxonium ions and ethanoate ions, but the back reaction is more successful than the forward one.
A strong acid is an acid which dissociates completely in water. That is, all the acid molecules break up into ions and solvate (attach) to water molecules. Therefore, the concentration of hydronium ions in a strong acid solution is equal to the concentration of the acid.

At 6400 km above the earth’s surface, an object weighing 71 N on the
surface would weigh only 18 N. Acceleration due to gravity will be about
¼ that on the surface of the earth.
