Answer: wavelength !!
hope this helped :)
S= 343m/s
F=256Hz
WL= 343ms/256-1
WL=V/F
= 1.339844m
A difference between the two forces is the fact that gravitation only attracts, while electrical forces attract when the electrical charges are opposite and repel if the charges are similar. Thus, gravitation is considered a monopole force, while electrostatics is a dipole force. Please mark me as a brainiest!!!
