the particles in liquids and gases move faster when they are heated than they do when they are cold. As a result, the particles take up more volume.
The sound bounces from wall to wall, so you draw arrows down the length of the canyon in both directions.
Answer:
d = 4.9 m
Explanation:
It is mentioned that a stone is dropped from a certain height. It is required to find the distance covered by it in one second.
The initial speed of the stone is equal to 0 as it was at rest. Let d is the distance covered by the stone.
Using second equation of motion :

Put u = 0 and a = g

So, the distance covered by it in one second is 4.9 m.
