Suppose an amoeba has 1.00 x 10 16 protons and a net charge of +0.3 pC (1pC = 10-12 C). If the protons and electrons are paired up which of the following statements is correct. A. There will be some unpaired protons B. There will be some unpaired electrons C. There will no unpaired e - /pA. There will be some unpaired protons When a glass rod is rubbed with silk, it becomes positive, and the silk becomes negative—yet both will attract dust.Does the dust have a third type of charge that...

A small metal ball is given a negative charge, then brought near to end A of the rod (positive charge on end, but mixed with neg. charge in center). What happens to end A of the rod when the ball approaches it closely this first time?It is attracted. After a great many contacts with the charged ball, how is the charge on the rod arranged (positive charge on end, but mixed with neg. charge in center);(when the charged ball is far away)?There is negative charge spread evenly on both ends....

unpolarized light will have electric components and magnetic components that are pointing in all directions. The electric field and direction of travel of light must always be perpendicular. The electric field of an electromagnetic wave is what determines the polarization the wave It is not possible for the axis of polarization of light, and the direction of travel of said light, to be parallel. All objects are going to emit some amount of light, called thermal radiation, because they ...
