Question

Read the excerpt from "Fountains of Aix” by May Swenson. Beards of water some of them have. Others are blowing whistles of water. Faces astonished that constant water jumps from their mouths. Jaws of lions are snarling water through green teeth over chins of moss. Dolphins toss jets of water from open snouts to an upper theater of water. Children are riding swans and water coils from the S-shaped necks and spills in flat foils from pincered bills. A solemn curly-headed bull puts out a swollen tongue of water. Which word best describes the tone created by the word placement in this excerpt? angry confused playful lonely

Answer 1

a = ½ ρ A/M v₁²

Step-by-step explanation:

This is a problem of fluid mechanics, where the jet of water at constant speed collides with a paddle, in this collision the water remains at rest, we write the Bernoulli equation, we will use index 1 for the jet before the collision the index c2 for after the crash

P₁ + ½ ρ v₁² + ρ g h₁ = P₂ + ½ ρ v₂² + ρ g h₂

in this case the water remains at rest after the shock, so v₂ = 0, as well as it goes horizontally h₁ = h₂

P₁-P₂ = ½ ρ v₁²

ΔP = ½ ρ v₁²

let's use the definition of pressure as a force on the area

F / A = ½ ρ v₁²

F = 1/2 ρ A v₁²

the density is

ρ = m / V

the volume is

V = A l

F = ½ m / l v₁²

knowing the force we can focus on the acceleration of the mass palette M

F = M a

a = F / M

a = ½ m/M 1/l v₁²

as well it can be given depending on the density of the water
