Question

Science answers please........

Answer 1

velocity 1550 m/s
time taken = 4 sec
1550 * 4= 6200 m
depth is half of the total = 6220/ 2
3100 m is thedepth

hope it helps

Answer 2

Hello friend

___________________________


Let write all the given values.

Given:

Velocity of sound in seawater = 1550 m/s

Time for echo to be heard = 4 s.

Time taken by sound waves to reach the bottom of the sea. = 4/2 = 2 s.


We know that,

Velocity = Distance/Time

Distance = Velocity x Time


So,by putting the given values we get,

Distance = velocity x Time

Distance = 1550 x 2

Distance = 3100 m


therefore,Depth of the sea at that place = 3100 m


Thanks..
