Pls answer both & show work thanks!

17. When light of wavelength 138 nm illuminates a metal the photoelectrons emitted have maximum kinetic energy equal to 8.07 eV. What will the photoelectron's maximum kinetic energy become when light of wavelength 391 nm shines on the same metal? 18. The nuclear weapon dropped on the city of Nagasaki in 1945 had an explosive yield (energy) of 20 kilotons. How much mass was converted directly to energy to produce that amount of energy
