Suppose an Oklahoman comes to Texas to go turkey hunting. He takes up camp 150 meters from the base of a cliff. When he sees a turkey he raises his shotgun, shoots, but misses (being a poor shot). He notices that he hears the echo of his gun off the cliff. How much time (in seconds) passes after the shot before the hunter hears the echo?

0.44s

Explanation:

Given parameters:

Distance from the turkey  = 150m

Unknown:

Time taken to hear the sound  = ?

Solution:

The speed of sound is the distance traveled per unit of time for a sound wave.

It is given as a constant which is 343m/s

As with this parameter:

         Speed  =  

         Time  =   =    = 0.44s

i think it is true since you can test the answer and can use observations to complete it.

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
