Hey Tori's are the rim of a canyon yells hello toward the opposite side she has an echo hello four seconds later if the speed of sound is 340 m/s how far away was the canyon wall that produced the echo?

The wall is 680 meter away from the person.

Explanation:

Given data

Speed of sound = 340

Given that Persons said hello toward the opposite side she has an echo hello 4 seconds later means it takes 2 seconds for the sound to reach the wall & again 2 seconds to reach the persons ear.

Therefore the distance between the person & wall is

D = speed × Time

D = 340 × 2

D = 680 meter

Therefore the wall is 680 meter away from the person.

answer: a. same unit

explanation:

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
