A 1 liter jar is filled with water right to the top. A rock is then dropped in the jar and 400 mL of water is displaced (pushed out). What is the volume of the rock?

The volume of the rock is equal to the volume of water it displaces. Since 400 mL of water is displaced when the rock is dropped into the jar, the volume of the rock is 400 mL.


What sound made by a rock falling into water?

A rock falling into water produces a splash sound, followed by ripples and bubbles as it sinks below the surface.


Does a hammer make a sound when it hits a rock in space?

Yes, the potential for sound is made by the energy of the impact - (sound will occur in the hammer and in the rock), BUT the sound never leaves the hammer/rock as there is no air in space though which the sound waves can propagate.


What will happen to the weight reading if a rock is dropped into water?

It depends what the weight reading was originally measuring. If it was measuring the weight of the experimenter and the rock they were holding, and the water is not being held by them, then the weight will decrease by the weight of the rock. If it was measuring the weight of the water into which the rock it dropped, then it will increase by the weight of the rock. If it was measuring the weight of something totally unrelated to the experiment, then dropping the rock will have no measurable effect on the reading of the weight. Context needs to be given for the weight reading for a proper answer to be given.

How is echo produce?

Imagine a pool of water. If you dropped a rock in the water you would cause ripples that would travel out evenly in all directions. When one of those ripples hits a wall, you can see that the ripple bounces off the wall. Sound works the same way. Sound is basically just ripples in the air (vibrations). When a sound vibration hits a wall it bounces back much like the ripples in water.


Is rock a good conductor of sound?

Probably. It depends on the crystal structure of the dominant mineral. A pourous rock, such as honeycomb rock in Jamaica, will not be a good conductor of sound. A dense rock, like granite, will conduct sound better.


How do you make sound but not all of it?

Sit on a rock and ponder the meaning of life.

Can a sound travel without atmosphere?

Sound can travel through water, metal, rock and air, so the atmosphere isn't strictly needed for sound transmission.
