Question

2 astronauts on the surface of moon cannot talk with each other WHY WHAT type of hearing are required by them

Answer 1

Explanation:

2 astronauts cannot talk with each other because there is no medium on moon for sound to travel,there is only vaccum.

Since sound waves are mechanical,They cannot propagate through vaccum.That's why they can't talk

They use radio waves to talk as radio waves are non mechanical and can propagate through vaccum
