Athin spherical shell with radius r1 = 4.00 cm is concentric with a larger thin spherical shell with radius r2 = 6.00 cm . both shells are made of insulating material. the smaller shell has charge q1=+6.00nc distributed uniformly over its surface, and the larger shell has charge q2=−9.00nc distributed uniformly over its surface. take the electric potential to be zero at an infinite distance from both shells.

High schoolphysics 5+3 pts a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows. if a fly lands on the glass tube, what will most likely happen? a) the fly will not feel a shock because the glass conducts any free electrons back into the gas. b) electrons will flow directly from the metal wires along the glass and shock the fly. c) the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal. d) electrons that are moving through the gas will be conducted through the glass and shock the fly.

Where is the potential energy throughout the loading, cocking, and releasing of the trebuchet?
