Answer: 2,464m
Explanation:
Echo made by a source is dependent on the velocity of the sound in air/water, the distance between the source and the reflector and the time taken
Using the echo formula
2x = vt
Where x is the distance between the source and the reflector
v is the velocity of the sound in sea water is approximately= 1540m/s (This varies from place to place and depending on the season and nature of water)
t is the time taken
t = 3.20s
Substituting this datas into the equation to get 'x'
2x = 1540 × 3.20
x = 1540×3.20/2
x = 2,464m
The distance between the object creating the echo is 2,464m

Answer:
gravity
Explanation:
Though gravity holds planets, stars, solar systems and even galaxies together, it turns out to be the weakest of the fundamental forces, especially at the molecular and atomic scales.
