Chlorine forms hydrochloric acid when reacted with hydrogen
Answer: A device records the time it takes sound waves to travel from the surface to the ocean floor and back again. Sound waves travel through water at a known speed. Once scientists know the travel time of the wave, they can calculate the distance to the ocean floor.
Explanation:
Average velocity of man is 2 m/s
<u>Given that;</u>
Distance between tree and house = 16 m
Time taken = 8 seconds
<u>Find:</u>
Average<em> velocity</em>
<u>Computation:</u>
Average velocity = Total distance cover / Time taken
Average velocity = Distance between tree and house / Time taken
Average velocity = 16 / 8
Average velocity = 2 m/s
