A ship produces ultrasonic sound which is collected in 8 s after reflection from the surface of sea. If the velocity of ultrasonics is `1531ms^-1`, then what is the distance of sea surface from sea ?

A message was transmitted from boat which returned to the sender after reflection from the bottom of the sea in 0.8 s. If the velocity of sound in water is 1500ms^-1 then find the depth of sea.

Ultrasonic signal sent from SONAR returns to it after reflection from a rock after a lapse of 1 sec. If the velocity of ultrasound in water is 1600 ms^(-1) , the depth of the rock in water is

A ship sends out ultrasound that returns form the seabed and is detected after 3.42 s . If the speed of the ultrasound through sea water is 1531 m//s , what is the distance of the seabed from the ship ?

Write the following statements in a sequential order to find the depth of the ocean bed by the using sonar . (A) The depth of the ocean bed can be found by d = (vt)/(2) . (B) At the bottom of a ship two devices , one is transmitter which products ultrasonics and a receiver for the detection of the reflected ultrasonics from the ocean bed are fixed . (C) The velocity fo ultrasonics in ocean water is 'v' and the time taken to receive the reflected ultrasonics from the ocean bed be 'f'. (D) If the depth of ocean bed is 'd' , then v = (d + d)/(t) = (2d)/(t) .

The echo of a gunshot is heard 10 seconds after it is fired. If the velocity of sound is 330 m/s, the distance of the surface which reflects the sound is
