- Describe one promising explanation for how thunderclouds become electrified, that is, acquire a charge separation that often leads to cloud-to-ground lightning strikes.The first Leyden jar was probably discovered by a German clerk named E. Georg von Kleist. Because von Kleist was not a scientist and did not keep good records, the credit for the discovery of the Leyden jar usually goes to physicist Pieter Musschenbroek from Leyden, Holland. Musschenbroek accidentally discovered the Leyden jar when he tried to charge a jar of water and shocked himself by touching the wire on the inside of the jar while holding the jar on the outside. He said that the shock was no ordinary shock and his body shook violently as though he had been hit by lightning. The energy from the jar that passed through his body was probably around 1 J, and his jar probably had a capacitance of about 1 nF. a. Estimate the charge that passed through Musschenbroeks body. b. What was the potential difference between the inside and outside of the Leyden jar before Musschenbroek discharged it?In an experiment there is an attraction of a charged object to the wall. Depicts the microscopic level mechanism for this observation. Identify the correct statements that apply when the object is positively charged.

A student has a neutrally charged glass rod and a neutrally charged silk cloth. When the student rubs the silk cloth on the glass rod, the rod acquires a net positive charge. What is the charge on the silk cloth after the student performs this experiment?A. the silk has no chargeB. the silk has a charge that is equal in magnitude to the glass rod’s charge, but it is negativeC. the silk is positively charged and has a greater magnitude of charge than the glass rodD. the silk is negatively charged and has a smaller magnitude of charge than the glass rod3.

- How is the electric field at the surface of a charged conductor related to the surface charge density? a) Proportional to each other b) Indirectly proportional c) Independent d) ExponentialI am struggling with understanding this review question, I have changed the numbers to practice the problem again later on. If I have a 2.5 gram copper penny and it has a charge of -2.0×10-9C (i) How many excess electrons are on the penny? (ii) By what percent do the excess electrons change the mass of the penny? If the penny's mass remains the same but the charge changes to 4.0×10-9C (iii) How many electrons have been removed from the penny? (iv) If only one electron is removed from the atom, what percent of the atoms are ionized by this charging process? Any help would be greatly appreciated :)1.
