Question

Short paragraph on Submarine​

Answer 1

Explanation:

A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. It is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as "boats" rather than "ships" irrespective of their size.[1]

Answer 2

A submarine (or Sub) is a vessel that goes underwater. Most large submarines are war vessels. Some small ones are used for scientific or business purposes. These are often called "submersibles" and cannot go far or stay long away from base.
