Assuming that the power plant for the electricity is 15 km away and uses 00-gauge copper wire (diameter 9.266 mm), how much power is dissipated in transmission (remember to count the return wire), if the power plant is directly providing the 110-v? (to be more precise, the power plant is providing the voltage it needs to provide, so that the voltage at the dorm room is 110 v.)

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.
