Seems Q was used because it refers the to "Quantity" of electrical charge.
The name of this symbol (;) is a semicolon. It is used between two clauses to link them rather than making them separate sentences (because they are too closely related to be separate).
On a spreadsheet you use the * symbol rather than x as used normally in mathematics.
Anything can be a safety symbol in a factory or anywhere else, as long as everyone understands that it is a safety symbol. Usually, symbols are used to indicate particular kinds of hazards, rather than "safety."
The SYMBOL for charge is q, the standard UNIT for charge is coulomb, and the abbreviation for the unit is C
Ca was already being used for calcium. Also, the second letter of the abbreviation is generally chosen to suggest the name of the element rather than being the literal second letter in the name.
Yes, the "prime" symbol (')can be used to denote minutes. The prime symbol looks similar to an apostrophe, but is a straight line. So, 10 minutes would be written as 10'. You didn't ask, but the double prime symbol can be used to denote seconds, as in 10".
The higher a charge an object has, the more propulsive or repulsive force it will have on another charged object. The equation for this is very similar to the one for gravity, accept there is a different constant and the charge is used rather than mass.

A symbol is a picture on a map. It is usually small and if you look it up in the map key it tells you what that symbol on the map is, and a little description of one or two words saying what that symbol means or stands for.
Usually the symbol ≥ is used to represent the words "greater than or equal to." ____ The greater than symbol is > and the equal to sign is =. The less than symbol is <.
In mathematics.
Electrons have an electric charge of −1.602 × 10−19 C,[2] which is used as a standard unit of elementary charge for subatomic particles. Within the limits of experimental accuracy, the electron charge is identical to the charge of a proton, but with the opposite sign.[48] As the symbol e is used for the constant of electrical charge, the electron is commonly symbolized by e−, where the minus sign indicates the negative charge.[2] This is what I found in Wikipedia. This would say that your answer sould be no.
