Two charged objects, a and b, are exerting an electric force on each other. what will happen if the charge on a is increased?

The force is proportional to the product of the charges. So if either one increases, the force between them increases.

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.

The rearrangement of particles in a physical change. hope this
