They wouldn't be able to talk with there helmets off
Sound is a compression/rarefaction wave in a material, such as air. There is no such thing on the moon.
because there is no sound in space and sound cannot travel through vacuum
no they cannot hear and talk but they have life and responsibility
Sound cannot travel in the vacuum of space because there is no air or medium for the sound waves to travel through. However, astronauts can communicate on the moon using radio systems and equipment inside their helmets that allow them to hear each other.
No, if you mute them they cannot hear you.
when we talk from a long distance the air in the atmosphere will break the voice so we cannot hear
Communications impaired
On the moon, there is no atmosphere to carry sound waves, so there is no medium for the sound to travel through and reach the other person's ears. As a result, sound cannot propagate in the same way it does on Earth, and communication through sound would not be possible between two individuals on the moon.
Well, you can get close to a plant and talk - about anything - the plant cannot hear, cannot sense your words, and cannot answer, but many plants do better when talked to regularly.
yes
Because there is no oxygen on the moon, so you can't talk.
Some people who cannot talk CAN hear. It depends on their particular disability. If a person is born deaf, it can keep them from learning to speak normally, and some people may have other reasons they can't talk, such as damage to their vocal cords.
