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...

24. Which of the following statements are correct? i) Hund's Rule states orbitals must be filled with electrons in order of lowest to highest energy. 11) The Aufbau Principle states that if electrons occupy degenerate orbitals, they must be half filled first. ill) The Heisenberg Uncertainty Principle states that the position and velocity of an electron cannot be determined simultaneously. iv) The ultraviolet catastrophe was that as the temperature of a blackbody increased, it would emit an infinite amount of...
