Please answer question i
thank you!
h) (4 pts) Ebonite, from which bowling balls are made is one of the most triboelectrically active substances. The precise mechanism for the triboclectric effect is still very much a scientific mystery. The surface of bonite will quickly pickup excess electrons as it moves through air. Moving charges comprise an electric current Oscillating electric currents generate radio waves. If the muss used in this question is ebonite, its oscillations will generate radio waves that...
