A scientific probe lands on several different planets, all of which have the same mass density ρ but differ in radius r. They measure the acceleration due to gravity g on the surface of each planet. Which of the followings shows a graph that can be used to determine an experimental value for the Universal Gravitational Constant G and an explanation of how to determine this value?

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.
