it basically means how far away its the earth its distance from matter
Pluto is classified as a dwarf planet
Answer:
twice as long
Explanation:
If Stardust managed to cover 50 miles on his first trip to the forest, and later managed to cover 300 miles by going 3 times faster, then we can easily come to the result as to how much more time Stardust needed comparably between the two trips, just by using these three numbers.
If Stardust was going 3 times as fast on the second trip, then we need to multiple that number with the number of miles of the first trip:
50 x 3 = 150
This means that Stardust managed to cover 150 miles on the second trip in the same amount of time as the 50 miles in the first trip. In order to see how much more time Stardust needed to cover the 300 miles, we just need to divide the total amount of miles, with the 150 miles of the 3 times faster speed:
300 / 150 = 2
So we get a result of 2, meaning that Stardust needed twice more time to cover the 300 miles, than what he needed to cover the 50 miles of the first trip.
Answer:
True
Explanation:
Kepler's second law states that for a planet orbiting a star, if we join the planet and the star by an imaginary line, such line sweeps equal areas in equal times.
Let's imagine the planetary orbit is elliptical. When the planet is closest to the star it travels a large distance in its orbit but takes little time to travel. When the planet is furthest from the star, it travels a small distance in the orbit but in a long time so it ends up sweeping the same are as in the first case.
Therefore, this means when the planet is closest to the star it must have a greater speed than when it's furthest. We know this thanks to the speed formula v = d/t (velocity equals distance divided by time).
For a great distance and small time, speed is a large value.
For a small distance and a great time, speed is a small value.
