Two slits are illuminated by a 568 nm light. the angle between the zeroth-order bright band at the center of the screen and the fourth-order bright band is 17.6 ◦ . if the screen is 176 cm from the double-slit, how far apart is this bright band from the central peak? answer in cm. answer in units of cm.

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.
