No sound is heard from the bell in the jar with the vacuum since:

• all air has been removed, and this has caused the bell to rust.

• all air has been removed, and sound requires a medium to travel.

• only gases are left in the jar, and sound cannot travel through gas.

• the vacuum is too loud and overpowers the sound of the bell

Since sound is the energy released by an object's vibrations, sound is a form of:

• elastic energy

• electric energy

• nuclear energy

• mechanical energy
