Hypothesize how the astronauts Neil Armstrong and Buzz Aldrin could talk to each other on the moon if the moon does not have an atmosphere for the sound waves to travel through?

Ithink the answer is d

Answerthe force between the charges will be  f/9 (one-ninth of force f)explanationcoulomb's law relates the magnitudes  two point charges q₁ and q₂, the distance, r, between the charges, and the electrostatic force, f, between the two charges:     k represents coulomb's constant, k = 8.99×10⁹ n·m²/c².note that if we have r = 3r, then   

Ithink c because you have to work to become goid
