Why can astronauts hear on moon if they come close to each other so that their helmets touch?
Normally, to communicate in space, astronauts need radios. This is because sound (in this case, speech) requires a medium (such as air) to move through. In space, since there is no air, astronauts cannot talk to one another directly.
However, in your case, the astronauts may converse because their helmets are touching - thus giving the sound waves a medium to move through - the helmets.

Why is it when 2 astronauts have their helmets touching they can hear each other why?
When astronauts touch their helmets, sound vibrations can travel through the material and air between the helmets, allowing them to hear each other. This method of sound conduction is known as bone conduction and helps transmit vibrations directly through solid surfaces, like the helmets, bypassing the need for air as a medium for sound.
If an astronaut's communication system breaks down NASA advise them to touch their helmets together WHY?
Touching helmets together can create a physical connection that may improve the transfer of sound vibrations between the two helmets, acting as a makeshift communication link. This can help the astronauts communicate in absence of a functioning communication system.
If an astronaut's radio broke what could they do to hear each other speak?
Touch helmets.
What equipment do astronauts use in space?
Astronauts use a variety of specialized equipment in space, such as spacesuits for extravehicular activities, helmets for protection, communication systems for staying in touch with mission control, and tools to carry out experiments or repairs on the spacecraft. They also have access to exercise equipment to maintain their physical health and well-being while in microgravity.
Do orb spiders live close to each other if so how close?
They form what looks like a sphere, or circilar form thus living so close they touch.
Why do astronaunts on the moon have to communnicate by radio even when close to one another?
Sound needs a medium to be transmitted in ... when we hear a sound it's just moving air. The air moves on our eardrums and THAT is how we hear .. on the moon there's basically no air for the sound to travel in .... .... it would be possible for astronauts on the moon to touch their helmets together and talk that way, if for example their radio was not working. ____________________________________________ They don't. Sound carries from the astronaut's mouth to his helmet, and if two astronauts were to touch their helmets together, the sound would be carried clearly to the second astronaut. However, if they are not actually touching helmets, the sound cannot be transferred through the vacuum of space. In that case, they would need to use either radio or some visual means of communication; visual hand signals, or a laser link, something like that. Or, for medium range verbal communication in space, you could use a version of the "two tin cans and a string" telephone. Attach a wire from one helmet to the other, and pull away so there is some tension in the string. Speak normally. The vibrations of the air inside your helmet will cause a vibration in the string. The vibration in the string will cause vibration in other helmet, and you will be able to hear. Not as well as a radio, and not as clearly - but it will work.
Can you touch planets?
No, it is not possible to physically touch planets as they are massive celestial bodies existing in space. Additionally, most planets in our solar system are composed of gas, rock, and other elements, making them uninhabitable and impossible to land on.
Why does the Venice fly trap have hairs?
Those "hairs" are sensors so if u touch it and touch the other sensors inside the "mouth" of the plant it will close thus trapping whatever is inside.
