- State which of the following statements are true and which are false: a) After two half-lives, all radioactive nuclei in a substance will have decayed. b) A resistor R and a capacitor C connected in parallel combine as = + à c) A photon travels along multiple paths from a star to a Geiger counter. d) The brighter the light illuminating a photocathode, the higher the energy of the electrons emitted. e) When a photon travels from a star to your eye, in its frame of reference the duration of its journey and the distance travelled are both zero.1. There are 82 protons in a lead nucleus. Why doesn't the lead nucleus burst apart? a) Coulomb repulsive force doesn't act inside the nucleus b) gravity overpowers the Coulomb repulsive force inside the nucleus c) the negatively charged neutrons balance the positively charged protons d) protons lose their positive charge inside the nucleus d) None of the other responses are correct2) Calculate the density of the nucleus if it had a radius of 10 cm.
