Which term describes an explosive device thrown by hand, dropped from an aircraft, or projected by some slow means?

The term that describes an explosive device thrown by hand, dropped from an aircraft, or projected by some slow means is "Bomb." Bombs can encompass a variety of explosive devices designed to be delivered via different methods, including aerial delivery or manual deployment. This broad classification includes various types of bombs that can be strategically used in military operations or demolition tasks.

In contrast, a projectile typically refers to objects that are propelled rather than specifically designed to be explosive devices. An "EBomb" often denotes an electronic bomb which usually targets electronic circuits rather than being a hand-thrown explosive. A mine, by definition, is a device placed on or just below the surface of the ground or in water, designed to explode when triggered, and is not intended to be thrown or dropped in the manner described in the question. Thus, the correct characterization of an explosive device, as stated in the question, aligns specifically with the definition of a bomb.
