A beam of laser light of wavelength 532.2 nm strikes a thin slit 0.00375 mm wide. After the light passes through the slit, what is the largest angle relative to the original direction of the beam at which the waves are completely canceled when viewed at a far distance from the slit? 3.56
7.12
1.58
9.24

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

not too sure thinking all accelerations are pointed down
