Suppose you have measured the diffraction pattern of a grating with d = 0.19 mm and have found that the spots were separated by s = 1.8 cm. now you want to determine d for an unknown grating. with the unknown grating, the spots are separated by s = 4.5 cm. what is d (mm)?

You are driving to the grocery store at 20 m/s. you are 110m from an intersection when the traffic light turns red. assume that your reaction time is 0.50s and that your car brakes with constant acceleration. how far are you from the intersection when you begin to apply the brakes? what acceleration will bring you to rest right at the intersection? how long does it take you to stop after the light changes? the known values: vi=20m/s xi=110m t=.50s vf=0m/s xf=0m a=?
