Using Planck's constant as h = 6.63 E-34 J*s, what is the wavelength of a proton with a speed of 5.00 E6 m/s? The mass of a proton is 1.66 E-27 kg.
The assignment is attached with this message.
Photons of wavelength 431 nm are incident ona metal. The most energetic electrons ejectedfrom the metal are bent into a circular arcof radius 18.2 cm by a magnetic field with amagnitude of 2.07 105 T.What is the work function of the metal?

I need help with the 2nd problem in the attached documents
1.) It has been estimated that the Earth contains 1.0 x 10^9 tons of natural uranium that can be mined economically. If all the world's energy needs (7.0 x 10^12 J/s) were supplied by 235(U) fission, how long would this supply last? Assume that the average energy released in a fission event...
