A garden hose with an internal diameter of 1.6 cm is connected to a (stationary) lawn sprinkler that consists merely of a container with 25 holes, each 0.30 cm in diameter. If the water in the hose has a speed of 0.96 m/s, at what speed does it leave the sprinkler holes?

s = 1.024 m/s

Explanation:

The volume of water passing through the hose(Vh) must equal the volume of water leaving the sprinkler(Vs)

Thus, using the volume of a cylinder, we have;

Vh = 0.96 x π x (1.6/2)²

Vh = 0.576π

Let s be the speed from the sprinkler. Thus;

Vs = s x 25 x π x (0.3/2)²

Vs = 0.5625π(s)

Since the condition is ;Vh = Vs

Thus,

0.576π = 0.5625π(s)

π will cancel out to give ;

0.576/0.5625 = s

s = 1.024 m/s

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.

i believe the answer is a hope it and is correct
