Two resistors have resistances r1 and r2. when the resistors are connected in series to a 12.7-v battery, the current from the battery is 1.81 a. when the resistors are connected in parallel to the battery, the total current from the battery is 9.06 a. determine r1 and r2. (enter your answers from smallest to largest.)

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.
