two attempts can not hear each other on the moon

1.	two attempts can not hear each other on the moon
Answer» Sound needs a medium to propagate.Sound cannot travel through vaccumThere is no atmosphere in moon -creating no vaccumTherefore sound cannot travel and they couldn't listen/hear each other We know that sound requires a medium to travel.When we speak then our sound travels through the air molecules.This makes vibrations in them and by those vibrations sound is heard by us.(This is the case of earth) Now consider the case of moon.In moon there is no air medium for the sound to travel.Hence,when we speak on moon we cannot hear each other.

*Sound needs a medium to propagate.*Sound cannot travel through vaccum*There is no atmosphere in moon -creating no vaccum*Therefore sound cannot travel and they couldn't listen/hear each other

We know that sound requires a medium to travel.When we speak then our sound travels through the air molecules.This makes vibrations in them and by those vibrations sound is heard by us.(This is the case of earth)

Now consider the case of moon.In moon there is no air medium for the sound to travel.Hence,when we speak on moon we cannot hear each other.
