amid [387]
A series of processes on Earth's surface and in the crust and in the mantle that slowly change rocks from one kind to another is called the rock cycle. This cycle is a group of changes. We all know that the rock has 3 kinds which are igneous rocks, the sedimentary rocks, and the metamorphic rocks. The igneous rocks in the rock cycle can change to the sedimentary rocks or to the metamorphic rocks. The sedimentary rocks can also change to the igneous rocks or to the metamorphic rocks. The metamorphic rocks can change to the igneous rocks or to the sedimentary rocks. All depends on the process it undergoes and the factors present to affect the change it undergoes.

Un observador se halla a 510m. de una pared. entre el observador y la pared, y a igual distancia de ambos, se realiza un disparo
ch4aika [34]

Answer:

a)    t = 0.75 s,  b)  t = 2.25 s

Explanation:

The speed of sound is constant in a material medium

           v = 340 m / s

we can use the relations of uniform motion to find the time

          v = x / t

          t = x / v

In the exercise, the observer's distance to the wall is indicated d = 510 m, it also indicates that the shot is fired at the midpoint

          x = d / 2

       

a) direct sound the distance from the observer to the screen is

           x = 510/2 = 255 m

           t = 255/340

           t = 0.75 s

b) echo sound.

In this case the sound reaches the wall bounces, the distance is

             x = d / 2 + d

             x = 3/2 d

             x = 3/2 510

             x = 765 m

the time is

              t = x / v

              t = 765/340

              t = 2.25 s
