An electron in a mercury atom changes from energy level b to a higher energy level when the
atom absorbs a single photon with an energy of 3.06 electronvolts.
determine the energy of the photon, in joules.

According to newton’s law of universal gravitation, which statements are true? as we move to higher altitudes, the force of gravity on us decreases. as we move to higher altitudes, the force of gravity on us increases. as we gain mass, the force of gravity on us decreases. as we gain mass, the force of gravity on us increases. as we move faster, the force of gravity on us increases.
