Question

what is one consequence of water being over 1000 times more dense then air?
sounds are much louder in water.
there is no sound in water.
there are no concequences.
it takes more energy to start a vibration.

Explanation:

To solve this, we analyze each option:

• "Sounds are much louder in water": Sound travels faster and can be louder in denser mediums like water (due to closer particles for vibration transfer), but the key consequence of high density (over 1000x air) is the energy needed to start vibration.
• "There is no sound in water": Incorrect, sound does travel in water.
• "There are no consequences": Incorrect, density affects sound propagation.
• "It takes more energy to start a vibration": Denser mediums (like water vs air) have more mass per volume, so more energy is required to initiate particle vibrations (since more mass needs to be moved). This matches the density difference's effect.

Answer:

It takes more energy to start a vibration.
