Abeam of photons with wavelength 150 nm and beam of electrons having the same energy as the photons go through the same slit of width 355 nm. you observe the diffraction pattern on a distant screen. all angles are measured from the centerline. the photons produce their first dark band at an angle α. is the magnitude of α bigger than, equal to, or smaller than the magnitude the angle, β, where the electrons produce their first dark band?

16. a brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 800 n on him. the mass of the losing player plus equipment is 90.0 kg, and he is accelerating at 1.20m/s2 size 12{1 "." "20"" m/s" rsup { size 8{2} } } {} backward. (a) what is the force of friction between the losing player’s feet and the grass? (b) what force does the winning player exert on the ground to move forward if his mass plus equipment is 110 kg? (c) draw a sketch of the situation showing the system of interest used to solve each part. for this situation, draw a free-body diagram and write the net force equation.
