Answer 1

Answer:

Answer. "Consider if the two astronauts are floating in the space they cannot talk to each other without using any special device because there is no medium of propagation of their sound waves in the space. In space, there is only vacuum. So, without any special device the two astronauts can't "talk to each other".
