yes but when you write it you don't but when you type it you do
B. Only Ted is correct, you do not need a space after a period with in an abbreviation any spell check will mark that wrong
Unlike the period at the end of a sentence (which have one or two spaces), the period following an abbreviation only needs one space. This is the general rule for abbreviations such as Dr., Jr., or Sr.
None and One.
Two times
It depends. If a space is put after the number, than it does need a period. (5 in.) If a space is not separating the numerical value and the abbreviation, then no. (5in) I have no clue why and think this is a really weird and pointless rule of the English language. :) Hope I could help
SPC is an abbreviation for "space", indicating the lot number within a mobile home community. When offered for sale, only the space and not the mobile home is included.

An abbreviation is a way to shorten a longer word in order to save space when writing. There is no current abbreviation for impressionism.
All you have to do is put a period. For Example: JIM ERIC COHEN = J.E.C (.) if its the end of a sentence.
Ellipses are space, period, space, period, space, period, space . . .
No, there is no full stop after cm. This is because cm isn't an abbreviation but a symbol; that is it represents centimetres, rather than being a shortening of centimetres. You should include a single space between the number and the symbol (35 cm).
No, it is no longer necessary to put two spaces after a comma used as punctuation. The modern convention is to use only one space after a comma.
