Final answer:
A U.S senator serves a six-year term. There are 100 senators, two from each state, and they have specific eligibility requirements such as age, citizenship duration, and state residency.
Step-by-step explanation:
A U.S senator has a six-year term. In the United States Senate, senators are elected to represent their states for a duration of six years, ensuring they have ample time to work on public policies and matters important to their constituents. There are 100 U.S. senators in total, with two senators representing each state. To be eligible for the Senate, a person must meet certain requirements, including being at least 30 years old, being a U.S. citizen for at least nine years, and residing in the state they wish to represent. Unlike the House of Representatives, where members are elected every two years, senators have less frequent elections, which allows them to be somewhat more insulated from short-term public opinion and pressures.
