. Radiation of a certain wavelength causes electrons with a maximum kinetic energy of 0.64 eV to be ejected from a metal whose work function is 2.60 eV. What will be the maximum kinetic energy with which this same radiation ejects electrons from another metal whose work function is 2.23 eV?

Asubmarine has a "crush depth" (that is, the depth at which water pressure will crush the submarine) of 250 m. what is the approximate pressure (water plus atmospheric) at this depth? (recall that the density of seawater is 1025 kg/m3, g = 9.81 m/s2, and 1 kg/(ms2) = 1 pa = 9.8692 10-6 atm.) a. 34.8 atm b. 24.8 atm c. 25.8 atm d. 7.8 atm

Asystematic approach to problem solving is called a (an)
