what values from question 1 should I use in my calculation for question 2? also where does the value for time go in that calculation?

Work Function 1/1 point (graded) Physical constants that you may need: Speed of light $$c=2.99792\times 10^8\frac{\mathrm{mI}}{\mathrm{s}}$$ Planck's constant $$h=6.62607\times 10^{?34}\mathrm{J}\mathrm{s}$$ electron Volt $$1\mathrm{eV}=1.60217\times 10^{?19}\mathrm{J}$$ Electrons with a kinetic energy of $$3.19\times 10^{?19}\mathrm{J}$$ are ejected from the surface of a metal plate upon irradiation by light with a frequency of $$1.29\times 10^{15}\mathrm{Hz}$$. Calculate the workfunction (in joules) of the metal. $$5.36?10^{?19}$$ Correct. You have used 7 of 10 attempts Save Correct ( $$1/1$$ point) Intensity of a Pulse of Light $$0.0/1.0$$ point (graded) Calculate the minimum intensity of light in watts $$\left(\frac{\mathrm{J}}{\mathrm{s}}\right)$$ required to eject $$4.75\times 10^{11}$$ electrons with a kinetic energy of $$1.36\times 10^{?19}\mathrm{J}$$ from the surface of the same metal plate as in the previous part of this problem, using a pulse of light with $$\mathrm{t}=0.20\mathrm{s}$$ duration.
