No, it is not necessary to end a sentence with two periods if the sentence ends with an abbreviation like "M.D." One period at the end of the abbreviation is sufficient for proper punctuation.
No, there should not be two periods when "am" is at the end of a sentence. Only one period is needed to end the sentence.
Because one period is signifying the shortened word (ie Dr.) and the other is just a period for the end of the sentence.
Using two periods at the end of a sentence is typically seen as a typographical error or a casual way of ending the sentence. It doesn't hold any specific meaning like an ellipsis or other punctuation marks.
If a sentence ends with a.m. or p.m., there is no need for an additional period after the period that is already part of the abbreviation. The period at the end of a.m. or p.m. serves as the ending punctuation for the sentence.
Never. When ending a sentence with an abbreviation, a single period will suffice. It does double duty in finishing the abbreviation and the sentence. You may, however, see three periods at the end of a sentence. This is an ellipses. Or, two periods may occur in a sentence that includes a quote. Example: When I heard him say, "I found your luggage.", I cried tears of joy.

One period. The period in etc. also functions as the period for the end of the sentence.
No. You can never have two periods at the end of a sentence. "He will arrive at 6 P.M."
Because one period is signifying the shortened word (ie Dr.) and the other is just a period for the end of the sentence.
An imperative sentence ends with either a period or an exclammation mark.
Commas do not go at the end of sentences. Periods go at the end of sentences. Generally when typing on a computer, you should have two spaces after the period at the end of a sentence.
One period at the end of a sentence is quite sufficient, even if the period serves two purposes (or perhaps even more). Two periods would be awkward.
To answer your question. You will have to put TWO periods.

no, there is only one. ================== I can't think of any example where ending a sentence with two periods would be necessary. Not even following the last word in a sentence that is being quoted within parentheses would I expect one to employ two periods. One, I humbly submit, is all that's ever needed. ------------------------- Placing more than one punctuation mark at the end of a sentence is superfluous. It is a rule of punctuation that there be only one form of "end punctuation" to a sentence. Whether the end punctuation be a period, question mark or exclamation point, only one is required. The rule applies also when the punctuation mark appears within parentheses or quotation marks; a second punctuation mark is both unnecessary and inappropriate.
