Ultraviolet light of wavelength 300 nm and intensity 1 ~W / m^2...

Ultraviolet light of wavelength 300 nm and intensity 1 W/m21 \mathrm{~W} / \mathrm{m}^2 falls on the surface of a photosensitive material. If one percent of the incident photons produce photoelectrons then the number of photoelectrons emitted per second from an area of 1 cm21 \mathrm{~cm}^2 of the surface is nearly
