Aviewing screen is separated from a double slit by 1.2 m. the distance between the two slits is 0.030 mm. monochromatic light is directed toward the double slit and forms an interference pattern on the screen. the second-order bright fringe (m = 2) is 4.5 cm from the center line on the screen. determine the wavelength of the light. calculate the distance between adjacent bright fringes.

Wo small variable-thrust jets are actuated to keep the spacecraft angular velocity about the z-axis constant at ? 0 = 1.16 rad/s as the two telescoping booms are extended from r1 = 1.18 m to r2 = 4.69 m at a constant rate over a period of 124 seconds. the small 19-kg experiment modules at the ends of the booms may be treated as particles, and the mass of the rigid booms is negligible. determine the necessary thrust t for each jet as a function of time where t = 0 is the time when the telescoping action is begun. after you have the general expression for t, answer the questions. show work.
