Because one period is signifying the shortened word (ie Dr.) and the other is just a period for the end of the sentence.
No, when using "OD" at the end of a sentence, you only need one period as the abbreviation already ends with a period. So it would be "O.D." with one period.
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.
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.
Two periods after a sentence are used to indicate an intentional pause or hesitation in speech, known as a "hesitation marker." This is common in informal writing or chat conversations when trying to convey a more casual or uncertain tone. However, it is not considered standard practice in formal writing.
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.

No. You can never have two periods at the end of a sentence. "He will arrive at 6 P.M."
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.

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.
