In 1.0s, 5.0x10^23 nitrogen molecules strike an area of8.0cm^2 at a speed of 300m/s. What is the pressure? (mass of one nitrogen molecule = 4.68x10^-26 kg.) I believe I should use 1/2mv ^2 for the solution but the answer I keep getting is nowhere near correct. Can someone help with this?
When a metal is illuminated with radiation with a wavelength of 152 nm, photoelectrons are ejected with a velocity of 7.9 x 10 5 m/s. What is the work function, in eV, of th
Q. The work function of a metal surface is 1.8 eV. Compute the threshold wavelength. Work function W = hγ o = h C / λ 0 λ 0 = h C / W = 6.626 X 10 -34 X 3 X 10 8
