Aphoton with a wavelength of 2.29 × 10^–7 meter strikes a mercury atom in the ground state.

based on your answer to question 79, state if this photon can be absorbed by the mercury atom.
explain your answer.

Two charged particles, q1 and q2, are located on the x-axis, with q1 at the origin and q2 initially at x1 = 12.2 mm. in this configuration, q1 exerts a repulsive force of 2.62 µn on q2. particle q2 is then moved to x2 = 18.0 mm. what is the force (magnitude and direction) that q2 exerts on q1 at this new location? (give the magnitude in µn.)
