Astronomical unit is that the average distance from the planet to the Sun, just about a hundred and fifty million klick. At its nighest purpose, Saturn is nine AU, then at its most distant purpose, it's 10.1 AU. Saturn's average distance from the Sun is 9.6 AU.
hope it helps!
Answer:
Athenian democracy developed around the 6th century BC in the Greek city-state (known as a polis) of Athens, comprising the city of Athens and the surrounding territory of Attica. Athenian democracy is often described as the first known democracy in the world. Other Greek cities set up democracies, most following the Athenian model, but none are as well documented as Athens' democracy.

As the text explains it will save lives by preventing show off's, drunk drivers, and road ragers from speeding down the road and causing accidents.
Answer: it represents ship trading routes for certain materials and slaves
Explanation: the arrows point across water which indicates that that is a ship route and the arrows have words on them so that also indicates that those things are bieng traded.
Answer:
The baseball would seem to be traveling with a velocity 0.98918c of 98.92% of the speed of light as seen from the Earth.
Explanation:
This problem involves the relativistic effects. The pitcher throws the ball with a velocity u' which is 65% of the speed of light c i.e. u' = 0.65c
The velocity V of the spaceship in which he is practicing is 95% of the speed of light. Therefore V = 0.95c
So if the ball is thrown in the same direction as the direction of the spacecraft's motion, then classically, the velocities would add up and exceed the speed of light. But we know that this is not possible. It is prohibited by the special theory of relativity. So we need to consider the relativistic addition of velocities to calculate the velocity (u) of the ball as seen from the Earth.
The formula for relativistic addition of velocities is expressed below,

We know that u' = 0.65c and V = 0.95c. now we can calculate u which is the velocity of the baseball as seen from Earth as follows


u = 0.98918c
So the baseball would seem to be traveling with a velocity 0.98918c of 98.92% of the speed of light as seen from the Earth.
