Question

an ultrasonic wave is sent from a ship towards a bottom of the sea it is found that the time interval between sending and receiving the wave is 1.5 seconds if the velocity of sound is 1400 M / s
in sea water calculate the depth of the sea​

Answer 1

Your answer is.......

depth of the sea = 2×speed ×time

speed =1400 m/s

time =1.5 seconds

actually depth of the sea is the distance ...

So, 2×1400×1.5

2×1400×15/10 (point will be emitted.)

we will cancel 10 by 1400 =140...

so 2 ×140 ×15 = 4200

ANSWER =4200 m

Hope it helps you.....

Answer 2

Answer:

Given, velocity(v)=1400m/s

and time(t)=1.5s

so,

the depth of sea (d) = Vt/2

= 1400*1.5/2

= 1400*15/20

= (70*15) m

=1050m

This is the perfect answer
