Select the correct text in the passage.

Which two words enhance the setting in this poem?

War

by Ellen Glasgow

Ripples of ribbons borne on high,  

Bloodstains upon a brazen sky;  

From cannon belching on the plain,  

Fire that by fire is fought again.  

A flash where steel by steel is met;  

A fume of smoke and blood and sweat.  

Sharp from the smeared and trodden gorse

The death-cry of a wounded horse.  

Dust of a plain ground into red  

By armies of majestic dead.  

Gaunt shadows on the changeless sky,  

A flock of vultures swarming nigh.  

Mid ashes where a hearth has stood,  

Children that cry aloud for food.  

Where green the peaceful highways run,  

A woman ravished in the sun.  

And far across the reeking sod  

A Nation sounding thanks to God.

Answer from plato is -Brazen and Reeking

Why is it important that home circuits are wired with parallel circuits?
Arlecino [84]

Answer:

Parallel circuits are used in homes because the loads can be operated independently of each other. That means that you can have an electrical item turned on and running without needing to have all of the other loads on and running as well.

¿Cuál es la aceleración centrípeta de un móvil que recorre una
Lady bird [3.3K]

Answer:

a)  a = 4.57 m/s², b)  a = 6.48 m / s² , c)  a = 1.42 m / s²,d)   r = 82.3 m

 

Explanation:

The centripetal acceleration is the acceleration responsible for the change of direction of the acceleration vector and occurs in circular movements, the expression is

           a = v² / r

let's apply this precaution to our cases

a) let's calculate

          a = 8²/14

         a = 4.57 m/s²

b) an automobile at v = 65 km / h (1000 m / 1km) (1 h / 3600 s) =18,055 m/s

let's reduce feet to meters

          1 ft = 0.3048 m

           r = 165 ft (0.3048 m / 1 ft) = 50.292 m

          a = 18,055 2 / 50,292

           a = 6.48 m / s²

c) we calculate

          a = 1.25²2 / 1.1

          a = 1.42 m / s²

d) we look for the radius

          a = v² / r

          r = v² / a

we reduce

          v = 80 km / h (1000 m / 1km) (1h / 3600s) = 22.22  ms

          r = 22.22²/6

          r = 82.3 m

e) the cenripeta acceleration is used to take the curves on the highway,

    Used in centrifuges to separate compounds

       It is used in the games of the park of atraccio

     Used in CD players and computer hard drives
