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 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.

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.

In a SONAR, ultrasonic waves are sent into the sea water and the reflected waves from a sunken ship are received after 2.0 s. If the velocity of waves in sea water is 1450 m s^(-1) , find the depth of the sunken ship.

A ship produces ultrasonic sound which is collected in 3.42 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 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 stationary (steady) ship transmits ultrasonic sound, that returns from the seabed, after the transmission it is received after 4s. If velocity of the ultrasonic sound in the sea is 1531 ms^(-1) then what is the distance of the seabed from the ship?
