Answer:

FLASH TO BANG RULE.

Explanation:

The “Flash-To-Bang” theory measures the time from when you see lightning to the time you hear the associated thunder. A measure of 5 seconds from Flash-To-Bang means lightning is one mile (1.6km) away. Ten seconds equals 2 miles (3.2km); 15 seconds equals 3 miles(4.8km).

Light travels faster than sound, so lightning will be seen before hearing it (the thunder is the sound of the lightning strike).

The speed of sound travels at around 340m/s, multiplied by 3 is about 1kilometer. So the number of seconds divided by 3 is how many kilometers away the lightning struck is.

The number of miles away a thunder struck is, can be calculated by dividing the seconds by 5.

What was the reason the Founding Fathers created a six-year term limit for members of the Senate? (1 point) Members should chang
sergey [27]

Answer:

The reason why the Founding Fathers created a six-year term limit for members of the Senate was:

B. So they could concentrate on the business of the government rather than reelection.

Explanation:

The idea behind the six-year term is stability, as was reasoned by James Madison. Senators could concentrate on doing their jobs instead of worrying about reelection very often. That would give them the chance to do a more stable job. Of course, to prevent Senators from losing touch with people and from becoming a way-too-powerful aristocracy, one-third of the Senators' terms would expire every two years, leaving two-thirds of the members in office.
