Final answer:
A Senator must be at least 30 years old, a U.S. citizen for at least nine years, and live in the state they represent. Senators serve six-year terms, and the Vice President of the United States breaks any ties in Senate votes.
Step-by-step explanation:
To be a Senator, one must meet specific age, citizenship, and residency requirements according to the United States Constitution. A Senator must be at least 30 years old, have been a citizen of the United States for a minimum of nine years, and, at the time of election, must be an inhabitant of the state they plan to represent.
Senators serve six-year terms, and elections are staggered so that one-third of the Senate seats are up for election every two years. This ensures a degree of continuity within the Senate.
In the case of a tie in a Senate vote, the Vice President of the United States serves as the President of the Senate and has the power to break the tie by casting the deciding vote. This role is crucial in closely contested legislative measures.
