Answer:
Explanation:
d = 42 meters
v = 12 m/s
t = ?
t = d/v
t = 42 / 12
t = 3.5 seconds. That's awfully fast.
Gravity can cause water to move down and carry sediment and rocks along the bottom. if the water slows down, it drops the rocks and if it floods a field then the grass will also filter smaller particles out leaving fine sediment behind. In addition to it the fast flow of water can cause erosion, over time it can cause valleys as well.

Answer:
Sound waves travel at 343 m/s through the air and faster through liquids and solids. The waves transfer energy from the source of the sound, e.g. a drum, to its surroundings. Your ear detects sound waves when vibrating air particles cause your ear drum to vibrate. The bigger the vibrations the louder the sound.
