A bond with elements from B.
I believe you ask about speed at the end of the hose:
The volume of the bucket is 225 liters which is equal to 225

.

Hose's cross section can be counted with the typical circle's area formula (with diameter instead of radius, that's why you've got a fraction):


are filled within 15 second.
As the bucket is being filled you can say that it's volume is the volume of the water that flowed out of the hose, then:

The speed of the water can be counted with equation:

After extracting h from the volume's equation you get:

When you count the fraction you get the answer:
Yo sup??
Average velocity=total distance covered/total time taken
total distance covered=4 + 8=12 miles
total time taken=6 hours
Therefore
average velocity=12/6
=2 miles/hour
Hope this helps
Heaver objects because they have greater mass
Answer:
empty space
Explanation:
Our solar system comprises of the sun as the star, the planets, the dwarf planets, various moons, and plenty of asteroids, comets, and meteoroids. However, the majority part of the solar system consists of a void or empty space. These empty spaces basically composed of planetary dust and gas.
Hence, it can be concluded that Most of our Solar system is composed of "Empty Spaces."
