(a) two protons in a molecule are 3.70 10-10 m apart. find the electric force exerted by one proton on the other. magnitude n direction (b) state how the magnitude of this force compares with the magnitude of the gravitational force exerted by one proton on the other.

The air that we breath is made mostly of which gaseous molecule

While standing outdoors one evening, you are exposed to the following four types of electromagnetic radiation: yellow light from a sodium street lamp, radio waves from an am radio station, radio waves from an fm radio station, and microwaves from an antenna of a communications system. rank these type of waves in terms of increasing photon energy.

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e
