An echo is a sound wave reflecting off an object. Sonar is a means of detecting object using sound waves, usually echoes.
You can find out the weight of an unknown object by using standard masses and a scale.
Whilst echoes are sound waves bouncing off, echolocation is when a sound is brought out by a predator, and they sense how it echoes. Through this way, predators, like the bat, can find the location of their prey without using eyesight.
That the speed of wind is taken to be negligible.
it measures the depth under water

Dolphins find their way using echolocation. Which is them sending out high pi pitched sounds and then listen for echoes to return.

Using boolen Contains(Object ob) method of List Interface .we can find object through List....

Water Displacement
You can find the volume of an object bigger than the graduated cylinder by using the displacement method using a beaker. The object also can be measured with a rules length, width, and height.
They HEAR using their ears but they use the echoes of the sounds they make to build a "sound picture" of their surroundings. This is used to avoid collisions and to catch prey. This use of sound and echoes is called "echo location".
you cant its inpoibl
depending on its mass, the time it took to travel you could find the speed of the object using Physics.
