A solid sphere of radius a is centered at the origin. It is made of an insulating material and carries a uniform charge density with total charge Qi. It is surrounded by a hollow, concentric conducting shell of inner radius b and outer radius c. The outer shell has total charge Q = -5 C. Required:
Compute the magnitude of the electric field at the point x = 30 cm on the x-axis.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
